        Warrant for the Purchase of Shares of Common Stock

No. 11-12-97                                    100,000 shares of
                                                     Common Stock

     FOR VALUE RECEIVED, PERMA-FIX ENVIRONMENTAL SERVICES, INC., a
Delaware corporation (the "Company"), hereby certifies that
DIONYSUS LIMITED ("Dionysus"), 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 from the date of this Warrant and ending at 5:00 p.m.
Eastern Daylight Savings Time on November 12, 2002 (the "Exercise
Period"), up to one hundred thousand (100,000) fully paid and
nonassessable shares of the Company's common stock, par value $.001
per share ("Common Stock"), at a purchase price of $1.70 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 share shall be
subject to adjustments from time to time as hereinafter provided in
this Warrant. This Warrant and all warrant of like tenor which may
be issued by the Company in exchange or substitution for, or upon
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 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

                                 2

          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

                                  3

          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.


                                 -4-

5.   Investment Representation and Transferability.  

     5.1  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 the applicable
          state securities laws 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 and the applicable state
          securities laws 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 and applicable state securities
               laws 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.

     5.2  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.

     5.3  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

                                 -5-
          respect to any proposed transfer or disposition of the
          Warrant or the Warrant Shares.

6.   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.

7.   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.

8.   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
