Re:  Perma-Fix  Environmental  Services,  Inc.; Form 10-K for fiscal year ended
     December 31, 2004 and Form 10-Q for fiscal quarter ended March 31, 2005;
     file No. 1-11596

Dear Ladies and Gentlemen:

The following are responses to the comments of the Securities and Exchange
Commission (the "SEC") with respect to Perma-Fix Environmental Services, Inc.
(the "Company") Form 10-K for the year ended December 31, 2004, File No. 1-11596
(the "Form 10-K"), and Form 10-Q for the quarter ended March 31, 2005 (the "Form
10-Q"), File No. 1-11596, that we received by letter dated June 10, 2005 (the
"Comment Letter"). The SEC's comments and the Company's responses thereto are
set forth below; numbered as such comments were numbered in the Comment Letter.
Page numbers referenced in responses indicate the pages of each respective
document. As denoted by the comment letter, revisions requested in the comment
letter will be included in our future filings beginning with, to the extent
practical, our Form 10-Q for the quarter ended June 30, 2005.

The Company acknowledges that:

     o    The Company is responsible for the adequacy and accuracy of the
          disclosure in the filing;

     o    Staff comments or changes to disclosure in response to staff comments
          do not foreclose the Commission from taking any action with respect to
          the filing; and

     o    The Company may not assert staff comments as a defense in any
          proceeding initiated by the Commission or any person under the federal
          securities laws of the United States.

Form 10-K for Fiscal Year Ended December 31, 2004

Contractual Obligations, page 32

1.   Please revise your table of contractual cash obligations to also include
     the following:
     (a) Estimated interest payments on your variable rate debt;

     (b) Estimated payments under interest rate swap agreements; and
     (c) Required ongoing environmental remediation efforts.

     Because the table is aimed at increasing transparency of cash flow, we
     believe these payments should be included in the table. Please also
     disclose any assumptions you made to derive these amounts.

Response:         (a) We will begin to include the estimated interest payments
                      of our variable rate debt in our next quarterly report on
                      Form 10-Q for the period ended June 30, 2005. We will
                      disclose the assumptions utilized to develop such
                      estimates, including interest rates and revolving loan
                      balances.

                  (b) Our interest rate swap payments for the quarter ended
                      March 31, 2005, was approximately $14,000 and we estimate
                      the payment for the quarter ended June 30, 2005 to be
                      approximately $12,000. In addition the interest rate swap
                      agreement terminates in December 2005. As such we feel the
                      amounts remaining are insignificant to the table and do
                      not see the benefit to including this amount.

                  (c) In an attempt to reduce redundancy in our filing, we had
                      not included the estimated spending on the current
                      environmental remediation, in this section, Contractual
                      Obligations, as it is also on pages 36 and 37 under the
                      heading Environmental Contingencies. We will include the
                      environmental contingency totals in the contractual
                      obligations table, but we propose to continue our
                      presentation and assumptions of environmental remediation
                      issues as a separate disclosure.

                      The contractual obligation table is presented below for
                      the fiscal year ended December 31, 2004, as if the changes
                      were made at that time. The footnotes to the table are
                      omitted except where new footnotes are added. All changes
                      to the disclosure are highlighted in bold letters.

                  (5) We have variable interest rates on our Term Loan and
                      Revolving Credit of 1 1/2% and 1% over the prime rate of
                      interest, respectively, and as such we have made certain
                      assumptions in estimating future interest payments on this
                      variable interest rate debt. We assume a renewal of the
                      debt at March 31, 2005 at a .5% reduction in the interest
                      rate, a 1.25% increase in prime rate during 2005, and
                      prime rate increases of .5% annually. We also anticipate
                      increasing our Term Loan balance at June 30, 2005, to the
                      original loan balance of $7,000,000. Additionally, we
                      assume a full repayment of our Revolving Credit by
                      December 2006, and full repayment of our Term Loan by May
                      of 2008.

                  (6) The environmental contingencies and related assumptions
                      are discussed further in the Environmental Contingencies
                      section of this Management's Discussion and Analysis, and
                      are based on estimated cash flow spending for these
                      liabilities.

Consolidated Statement of Cash Flows, page 51

2.   We note your classification of $192,000 related to the issuance of common
     stock for services in non-cash investing and financing activities. Tell us
     the nature of the services provided and why this amount is not more
     appropriately reflected as an adjustment to reconcile net loss to net cash
     flows provided by operating activities within your consolidated statement
     of cash flows.

Response:             The $192,000 of common stock issued for services, is
                      related to issuance of common stock for payment of fees to
                      our board of directors. We separated that amount out in
                      the supplemental information as it was a non-cash
                      issuance. In addition the amount is included as an
                      adjustment of accrued expenses to arrive at net cash
                      provided by operations. In future filings we will
                      eliminate the supplemental disclosure and separate the
                      amount from the accrued expense adjustment in the cash
                      flow statement under operating cash flow.

                  The Consolidated Statements of Cash Flows is presented below
                  for the fiscal years ended December 31, 2004, 2003, and 2002,
                  as if the changes were made at that time. All changes to the
                  disclosure are highlighted in bold.

3.   Please reconcile for each period presented your segment profit or loss to
     your consolidated income before income taxes, discontinued operations, and
     the cumulative effect of changes in accounting principles. See paragraph
     32.b. of SFAS 131.

Response:             In our annual financial statement footnotes we have
                      historically reported our "segment profit (loss)" as
                      consolidated income before income taxes, discontinued
                      operations and cumulative effect of changes in accounting
                      principles, but have included preferred dividends as it is
                      an allocated amount. In future filings we will eliminate
                      preferred dividends from our segment profit amount, and
                      thus the segment profit or loss will tie directly to the
                      consolidated income before income taxes, discontinued
                      operations and cumulative effect of changes in accounting
                      principles reported in our Consolidated Statements of
                      Operations, and there will be no need for a
                      reconciliation.
