                  PERMA-FIX ENVIRONMENTAL SERVICES, INC.

            Warrant for the Purchase of Shares of Common Stock

No. 7-9-96                                                100,000 shares of
September 16, 1996                                             Common Stock

     FOR VALUE RECEIVED, PERMA-FIX ENVIRONMENTAL SERVICES, INC. (the
"Company"), a Delaware corporation, hereby certifies that MARVIN S.
ROSEN, or any permitted assignee thereof (the "Holder"), is entitled
to purchase from the Company, at any time in whole, or from time 
to time in part, during the period commencing January 1, 1997, and
ending at 5:00 p.m. Eastern Standard Time on September 15, 1999 (the
"Exercise Period"), up to one hundred thousand (100,000) fully paid
and nonassessable shares of common stock, $.001 par value, of the
Company (the "Common Stock"), at a purchase price of $1.75 per
share; provided, however, that the number of shares of Common Stock
to be issued and delivered by the Company upon any exercise of this
Warrant and the purchase price to be paid for each such share shall
be subject to adjustment from time to time as hereinafter provided
in this Warrant.  This Warrant and all warrants of like tenor which
may be issued by the Company in exchange or substitution for, or
upon the transfer or partial exercise of, this Warrant are
hereinafter collectively referred to as the "Warrants"; the shares
of Common Stock issuable and issued upon exercise of the Warrants
are hereinafter collectively referred to as the "Warrant Shares" and
the price payable for each of the Warrant Shares upon such exercise
is hereinafter referred to as the "Warrant Price".

1.   Exercise of Warrant.  This Warrant may be exercised, as a whole
at any one time or in part from time to time, during the Exercise
Period, by the Holder by the surrender of this Warrant (with the
subscription form at the end hereof duly executed by the Holder) at
the address set forth in Section 9 hereof, together with payment in
the manner hereinafter set forth, of an amount equal to the Warrant
Price in effect at the date of such exercise multiplied by the total
number of Warrant Shares to be purchased upon such exercise. 
Payment for Warrant Shares shall be made by a cashier's or certified
check or money order, payable in New York Clearing House funds, to
the order of the Company.  If this Warrant is exercised in part,
such exercise shall be for a whole number of Warrant Shares and the
Holder shall be entitled to receive a new Warrant covering the
number of Warrant Shares in respect of which this Warrant has not


been exercised.  Upon any exercise and surrender of this Warrant,
the Company (a) will issue and deliver to the Holder a certificate
or certificates in the name of the Holder for the largest whole
number of Warrant Shares to which the Holder shall be entitled and,
if this Warrant is exercised in whole, in lieu of any fractional
Warrant Share to which the Holder otherwise might be entitled, cash
in an amount equal to the fair value of such fractional share
(determined in such reasonable manner as the Board of Directors of
the Company shall determine), and (b) will deliver to the Holder
such other securities and properties which the Holder may be
entitled to receive upon such exercise, or the proportionate part
thereof if this Warrant is exercised in part, pursuant to the
provisions of this Warrant.

2.   Reservation of Warrant Shares.  

     2.1  The Company covenants and agrees that all Warrant Shares
          which may be acquired by the Holder under this Warrant
          will, when issued and upon delivery, be duly and validly
          authorized and issued, fully paid and nonassessable, and
          free from all restrictions on the sale or transfer
          thereof, except such restrictions as may be imposed under
          applicable federal and state securities laws and
          applicable exchange on which the Common Stock may be
          listed, and free and clear of all preemptive rights.

     2.2  The Company covenants and agrees that it will, at all
          times, reserve and keep available an authorized number of
          shares of its Common Stock and other applicable
          securities sufficient to permit the exercise in full of
          this Warrant; and, if at the time the number of
          authorized but unissued shares of Common Stock shall not
          be sufficient to effect the exercise of this Warrant, the
          Company will take such corporate action at its next
          annual meeting of stockholders as may be necessary to
          increase its authorized but unissued shares of Common
          Stock to such number of shares as shall be sufficient for
          such purpose, including, without limitation, engaging in
          reasonable efforts to obtain the requisite stockholder
          approval of any necessary amendment to its Certificate of
          Incorporation.

3.   Protection Against Dilution. 

     3.1  If, at any time or from time to time after the date of
          this Warrant, the Company shall distribute pro rata to
          all of the holders of its then outstanding shares of
          Common Stock (a) securities, other than shares of Common
          Stock or stock options, or (b) property, other than cash,
          without payment therefor, then, and in each such case,
          the Holder, upon the exercise of this Warrant, shall be


          entitled to receive the securities and property which the
          Holder would hold on the date of such exercise if, on the
          date of this Warrant, the Holder had been the holder of
          record of the number of shares of the Common Stock
          subscribed for upon such exercise and, during the period
          from the date of this Warrant to and including the date
          of such exercise, had retained such shares and the
          securities and properties receivable by the Holder during
          such period.

     3.2  If, at any time or from time to time after  the date of
          this Warrant, the Company shall (a) pay a dividend on its
          Common Stock in shares of Common Stock, (b) subdivide its
          outstanding shares of Common Stock into a greater number
          of shares, (c) combine its outstanding shares of Common
          Stock into a smaller number of shares, or (d) issue by
          reclassification of its Common Stock any shares of any
          other class of capital stock of the Company, the number
          of Warrant Shares and the Warrant Price in effect
          immediately prior to such event shall be adjusted so
          that, upon exercise of this Warrant, the Holder shall be
          entitled to purchase under this Warrant, without
          additional consideration therefor, the number of shares
          of Common Stock or other capital stock of the Company
          which he would have owned or been entitled to purchase
          immediately following the happening of any of the events
          described above in this subsection 3.2 had this Warrant
          been exercised and the Holder become the holder of record
          of the Warrant Shares purchased upon such exercise
          immediately prior to the record date fixed for the
          determination of stockholders entitled to receive such
          dividend or distribution or  the effective date of such
          subdivision, combination or reclassification at a Warrant
          Price equal to the aggregate consideration which the
          Holder would have had to pay for such Warrant Shares
          immediately prior to such event divided by the number of
          Warrant Shares the Holder is entitled to receive
          immediately after such event.  An adjustment made
          pursuant to this subsection 3.2 shall become effective
          immediately after the record date in the case of a
          dividend or distribution and shall become effective
          immediately after the effective date in the case of a
          subdivision, combination or reclassification.  If, as a
          result of an adjustment made pursuant to this subsection
          3.2, the Holder of this Warrant thereafter surrendered
          for exercise shall become entitled to receive shares of
          two or more classes of capital stock or shares of Common
          Stock and any other class of capital stock of the
          company, the Board of Directors (whose determination
          shall be conclusive and shall be described in a written
          notice to all holders of the Warrants promptly after such


          adjustment) shall determine the allocation of the
          adjusted Warrant Price between or among shares of such
          classes of capital stock or shares of Common Stock and
          such other class of capital stock.

     3.3  In case of any consolidation or merger to which the
          Company is a party, other than a merger or consolidation
          in which the Company is the continuing or surviving
          corporation, or in case of any sale or conveyance to
          another entity of all or substantially all of the
          property of the Company as an entirety or substantially
          as an entirety, the Holder of this Warrant shall have the
          right thereafter, upon exercise of this Warrant, to
          receive the kind and amount of securities, cash or other
          property which he would have owned or been entitled to
          receive immediately after such consolidation, merger,
          sale or conveyance had this Warrant been exercised
          immediately prior to the effective date of such
          consolidation, merger, sale or conveyance and in any such
          case, if necessary, appropriate adjustment shall be made
          in the application thereafter of the provisions of this
          Section 3 with respect to the rights and interests of the
          Holder of this Warrant to the end that the provisions of
          this Section 3 thereafter shall be correspondingly
          applicable, as nearly as may reasonably be, to such
          securities and other property.  Notice of any such
          consolidation, merger, sale or conveyance, and of said
          provisions so proposed to be made, shall be mailed to the
          Holder not less than thirty (30) days prior to such
          event.  A sale of all, or substantially all, of the
          assets of the Company for a consideration consisting
          primarily of securities shall be deemed a consolidation
          or merger for the foregoing purposes.

4.   Fully Paid Stock; Taxes.  The Company agrees that the shares
of the Common Stock represented by each and every certificate for
Warrant Shares delivered upon the exercise of this Warrant shall,
at the time of such delivery, be validly issued and outstanding,
fully paid and nonassessable, and not subject to preemptive rights,
and the Company will take all such actions as may be necessary to
assure that the par value or stated value, if any, per share of the
Common Stock is at all times equal to or less than the Warrant
Price.  The Company further covenants and agrees that it will pay,
when due and payable, any and all federal and state stamp, original
issue or similar taxes which may be payable in respect of the
issuance of any Warrant Share or certificate therefor.

5.   Registration Under Securities Act of 1933.  

     5.1  Subject to the terms of this Section 5, if, at any time
          during the Exercise Period, the Company receives a


          written request from the Holder (whether or not the
          Holder theretofore shall have exercised this Warrant in
          whole or in part), and provided that (a) at the time of
          such request the Holder is the owner of, and/or has the
          right pursuant to this Warrant to purchase, Warrant
          Shares representing at least fifty percent (50%) of the
          total number of Warrant Shares, and (b) the Company has
          not theretofore included within the coverage of a
          Registration Statement filed by the Company with the
          Securities and Exchange Commission ("Commission") under
          the Securities Act of 1933, as amended (the "Act"), which
          Registration Statement has been declared effective by the
          Commission, at least fifty percent (50%) of the Warrant
          Shares, the Company promptly shall prepare and file with
          the Commission a Registration Statement under the Act
          covering all of the Warrant Shares theretofore issued and
          which thereafter may be issuable upon the exercise of
          Warrants (provided, that the audited financial statements
          to be included in such Registration Statement shall be
          the year-end financial statements customarily included in
          the Company's Annual Report on Form 10-K under the
          Securities Exchange Act of 1934 (the "Exchange Act"), and
          provided further, that, if the request for registration
          is received within three (3) months prior to the
          commencement of a fiscal year of the Company, the Company
          may delay the preparation and filing of such Registration
          Statement for a period of not more than ninety (90) days
          following the commencement of such fiscal year in order
          to prepare and include in such Registration Statement
          audited financial statements for the immediately
          preceding fiscal year), shall use its reasonable efforts
          to cause such Registration Statement to become effective
          and to remain effective and current with respect to the
          Warrant Shares for an aggregate period of one (1) year
          (exclusive of any period during which the prospectus
          included therein shall not meet the requirements of
          Section 10 of the Act) and shall take all other action
          necessary or appropriate to cause the prospectus included
          therein to be available for the sale of Warrant Shares
          from time to time during such period by the holders
          thereof in ordinary brokerage transactions in the over-
          the-counter market or on any national securities exchange
          on which the Common Stock is then listed. The right to
          demand the filing of a Registration Statement pursuant to
          this subsection 5.1 shall be exercisable on one (1)
          occasion only.  The Holder's rights under this Section
          5.1 shall expire and terminate at the earlier of (a) such
          time as the Holder shall receive from counsel for the
          Company a written opinion of such counsel that the Holder
          has the right, pursuant to Rule 144 promulgated under the
          Act, to sell as of the date of such opinion, any portion


          of the Warrant Shares then held and/or purchasable upon
          the exercise of this Warrant by the Holder, or (b) upon
          a Registration Statement being declared effective by the
          Commission in which the Company has included at least
          fifty percent (50%) of the Warrant Shares within the
          coverage of such Registration Statement.

     5.2  Whenever the Company includes Warrant Shares in a
          Registration Statement, the Company shall (a) furnish the
          Holder of Warrant Shares included in such Registration
          Statement and each underwriter of such Warrant Shares
          with such copies of a current prospectus, including the
          preliminary prospectus, conforming to the requirements of
          Section 10 of the Act (and such other documents as each
          such Holder or each such underwriter may reasonably
          request), as such Holder(s) and underwriter(s) may
          reasonably require in order to effectuate the offer and
          sale of the Warrant Shares included in such Registration
          Statement; (b) use its reasonable efforts to register or
          qualify such Warrant Shares under the blue sky laws (to
          the extent applicable) of such jurisdiction or
          jurisdictions which the Company deems appropriate or
          necessary, provided, however, that the Company shall not
          be obligated to register or qualify any Warrant Shares
          under those "blue sky" securities laws which the Company
          deems are unduly burdensome in connection with such
          registration or qualification of Warrant Shares in such
          state; and, (iii) take such other actions as may be
          reasonably necessary or advisable to enable such
          Holder(s) and such underwriters to consummate the sale or
          distribution in such jurisdiction or jurisdictions in
          which such Holder(s) shall have reasonably requested that
          the Warrant Shares be sold; provided, however, that the
          Company shall not be required to qualify as a foreign
          corporation or broker-dealer in any jurisdiction or to
          file a consent to service of process in any jurisdiction
          in any action other than one arising out of the offering
          or sale of the Warrant Shares.

     5.3  The Company shall pay all expenses incurred in connection
          with any registration of the Warrant Shares pursuant to
          the provisions of this Section 5, except underwriting
          discounts, brokerage commissions, and applicable
          insurance and transfer taxes relating to the sale of the
          Warrant Shares are to be paid by the Holder, and, should
          the Holder elect to be separately represented by counsel,
          the fees and disbursements payable to such counsel for
          the Holder shall be paid by the Holder.


     5.4  In the event the Company includes any Warrant Shares in
          a Registration Statement filed by the Company with the
          Commission:

          5.4.1     Except as otherwise provided in this Section
                    5.4, to the extent permitted by law, the
                    Company will indemnify and hold harmless the
                    Holder and each other entity or person, if any,
                    controlling the Holder within the meaning of
                    either Section 15 of the Act or Section 20 of
                    the Exchange Act (collectively, the
                    "Controlling Party"), against any losses,
                    claims, damages or liabilities to which the
                    Holder or the Controlling Party may become
                    subject under the Act, insofar as such losses,
                    claims, damage or liabilities (or actions in
                    respect thereof) arise out of, or are based on,
                    any untrue or alleged untrue statement of any
                    material fact contained in such Registration
                    Statement registering the Warrant Shares filed
                    by the Company with the Commission, including
                    any preliminary prospectus or final prospectus
                    contained therein or any amendments or
                    supplements thereto, or arise out of, or are
                    based upon, the omission or alleged omission to
                    state therein a material fact required to be
                    stated therein, or necessary to make the
                    statements therein not misleading or arise out
                    of any violation by the Company of any rule or
                    regulation promulgated under the Act applicable
                    to the Company and relating to action or
                    inaction required of the Company in connection
                    with any such registration; provided, however,
                    that the indemnity agreement contained in this
                    Section 5.4.1 shall not apply to amounts paid
                    in settlement of any such loss, claim, damage,
                    liability or action if such settlement is
                    effected without the consent of the Company
                    (which consent shall not be unreasonably
                    withheld) nor shall the Company be liable in
                    any such case for any such loss, claim, damage,
                    liability, or action to the extent that it
                    arises out of, or is based upon, any untrue
                    statement or alleged untrue statement or
                    omission or alleged omission made in connection
                    with such Registration Statement, preliminary
                    prospectus, final prospectus, or amendments or
                    supplements thereto, in reliance upon, and in
                    conformity with, written information furnished
                    expressly for use in connection with such


                    Registration Statement by the Holder, any
                    underwriter or Controlling Party thereof.

          5.4.2     Except as otherwise provided in this Section
                    5.4, to the extent permitted by law, the Holder
                    will indemnify and hold harmless the Company,
                    each of its directors, each of its officers who
                    have signed the Registration Statement that
                    includes Warrant Shares, each person, if any,
                    who controls the Company within the meaning of
                    the Act or the Exchange Act, and each agent for
                    the Company against any losses, claims,
                    damages, or liabilities to which the Company or
                    any such director, officer, controlling person,
                    agent, or underwriter may become subject under
                    the Act, insofar as such losses, claims,
                    damages or liabilities (or actions in respect
                    thereto) arise out of, or are based upon, any
                    untrue statement or alleged untrue statement of
                    a material fact contained in such Registration
                    Statement, including any preliminary prospectus
                    or final prospectus contained therein or any
                    amendments or supplements thereto, or arise out
                    of, or are based upon, the omission or alleged
                    omission to state therein a material fact
                    required to be stated therein or necessary to
                    make the statements therein not misleading, in
                    each case to the extent, but only to the
                    extent, that such untrue statement or omission
                    or alleged untrue statement or omission was
                    made in such Registration Statement,
                    preliminary or final prospectus or amendments
                    or supplements thereto, in reliance upon, and
                    in conformity with, written information
                    furnished by, or on behalf of, the Holder for
                    use in connection with such Registration
                    Statement; provided, however, that the
                    indemnity agreement contained in this section
                    5.4.2 shall not apply to amounts paid in
                    settlement of any such loss, claim, damage,
                    liability or action if such settlement is
                    effected without the consent of the Holder
                    (which consent shall not be unreasonably
                    withheld), and that the obligation of the
                    Holder hereunder shall be limited to an amount
                    equal to the proceeds to the Holder of Warrant
                    Shares sold pursuant thereto.

          5.4.3     Promptly after receipt by a person entitled to
                    indemnification pursuant to this Section 5.4
                    (an "Indemnified Party") of notice of the


                    commencement of any action, the Indemnified
                    Party will, if a claim in respect thereof is to
                    be made against the indemnifying party under
                    this Section 5.4, notify in writing the
                    indemnifying party of the commencement thereof,
                    but the omission so to notify the indemnifying
                    party will not relieve it from any liability
                    which it may have to the Indemnified Party
                    otherwise than under this Section.  In case any
                    such claim or action is brought against an
                    Indemnified Party and it notifies the
                    indemnifying party of the commencement thereof,
                    the indemnifying party will be entitled to
                    participate in and, to the extent that it may
                    wish, jointly with any other indemnifying party
                    similarly notified, to assume the defense
                    thereof, subject to the provisions herein
                    stated, with counsel reasonably satisfactory to
                    the Indemnified Party, and after notice from
                    the indemnifying party to the Indemnified Party
                    of its election so to assume the defense
                    thereof, the indemnifying party will not be
                    liable to the Indemnified Party under this
                    Section 5.4 for any legal or other expenses
                    subsequently incurred by the Indemnified Party
                    in connection with the defense thereof.  The
                    Indemnified Party shall have the right to
                    employ separate counsel in any such action and
                    to participate in the defense thereof, but the
                    fees and expenses of such counsel shall be paid
                    by the Indemnified Party, except that the
                    indemnifying party shall pay such reasonable
                    fees and expenses of such counsel only in the
                    event that (a) the employment of such counsel
                    has been specifically authorized in writing by
                    the indemnifying party and the indemnifying
                    party has agreed, in writing, to pay such fees
                    and expenses, or (b) the named parties to any
                    such action (including any impleaded parties)
                    include both the Indemnified Party or parties
                    and the indemnifying party and the Indemnified
                    Party has been advised by counsel for the
                    indemnifying party that there are defenses
                    available to it or them that the indemnifying
                    party or its counsel refuses to accept or
                    counsel for the indemnifying party reasonably
                    determines that there may be a conflict between
                    the position of the indemnifying party and the
                    Indemnified Party in conducting the defense of
                    such action, then counsel for the Indemnified
                    Party (at the indemnifying party's expense)
      

                    shall be entitled to conduct only that part of
                    the Indemnified Party's or parties' defense
                    that counsel for the indemnifying party
                    declines to, or cannot, conduct because of the
                    foregoing reasons, it being understood,
                    however, that the indemnifying party or parties
                    shall not, in connection with any one such
                    action or separate, but substantially similar
                    or related actions in the same jurisdiction
                    arising out of the same general allegations or
                    circumstances, be liable for the reasonable
                    fees and expenses of more than one (1) separate
                    firm of attorneys for all such Indemnified
                    Party or parties.

6.   Investment Representation and Transferability.  

     6.1  By acceptance hereof, the Holder represents and warrants
          that this Warrant is being acquired, and all Warrant
          Shares to be purchased upon the exercise of this Warrant
          will be acquired, by the Holder solely for the account of
          such Holder, and not with a view to the fractionalization
          and distribution thereof, and will not be sold or
          transferred except in accordance with the applicable
          provisions of the Act and the rules and regulations of
          the Commission promulgated thereunder.  The Holder
          covenants and agrees that this Warrant and the Warrant
          Shares will not be sold or transferred except under cover
          of a Registration Statement under the Act which the
          Commission has declared effective and which is current
          with respect to such Warrant and the Warrant Shares or
          pursuant to an opinion of counsel reasonably satisfactory
          to the Company that registration under the Act is not
          required in connection with such sale or transfer.  Any
          Warrant Shares issued upon exercise of this Warrant shall
          bear the following legend:

               The securities represented by this certificate
               have not been registered under the Securities
               Act of 1933, as amended, and are restricted
               securities within the meaning thereof.  Such
               securities may not be sold or transferred
               except pursuant to a Registration Statement
               under such Act which is effective and current
               with respect to such securities or pursuant to
               an opinion of counsel reasonably satisfactory
               to the issuer of such securities that such sale
               or transfer is exempt from the registration
               requirements of such Act.



     6.2  The Holder agrees that the Company may refuse to permit
          the sale, transfer or disposition of this Warrant or any
          of the Warrant Shares unless there is in effect a
          Registration Statement under the Act and any applicable
          state securities law covering such transfer or the Holder
          furnishes an opinion of counsel, reasonably satisfactory
          to counsel for the Company, to the effect that such
          registration is not required.

     6.3  The Holder understands that under the Act, this Warrant
          and the Warrant Shares must be held indefinitely unless
          they are subsequently registered under the Act or unless
          an exemption from such registration is available with
          respect to any proposed transfer or disposition of the
          Warrant or the Warrant Shares.

7.   Loss, etc. of Warrant.  Upon receipt of evidence satisfactory
to the Company of the loss, theft, destruction or mutilation of this
Warrant, and of indemnity reasonably satisfactory to the Company,
if lost, stolen or destroyed, and upon surrender and cancellation
of this Warrant, if mutilated, and upon reimbursement of the
Company's reasonable incidental expenses, the Company shall execute
and deliver to the Holder a new Warrant of like date, tenor and
denomination.

8.   Warrant Holder Not Shareholder.  This Warrant shall not be
deemed to confer upon the Holder any right to vote or to consent to
or receive notice as a shareholder of the Company, as such, in
respect of any matters whatsoever, or any other rights or
liabilities as a shareholder, prior to the exercise hereof.

9.   Notices.  Except as otherwise specified herein to the contrary,
all notices, requests, demands and other communications required or
desired to be given hereunder shall only be effective if given in
writing, by hand or fax, by certified or registered mail, return
receipt requested, postage prepaid, or by U. S. Express Mail
service, or by private overnight mail service (e.g., Federal
Express).  Any such notice shall be deemed to have been given (a)
on the business day actually received if given by hand or by fax,
(b) on the business day immediately subsequent to mailing, if sent
by U.S. Express Mail service or private overnight mail service, or
(c) five (5) business days following the mailing thereof, if mailed
by certified or registered mail, postage prepaid, return receipt
requested, and all such notices shall be sent to the following
addresses (or to such other address or addresses as a party may have
advised the other in the manner provided in this Section 9) to:
