Section 1 - Registrant's Business and Operations.

Item 1.01.  Entry into a Material Definitive Agreement.

     On June 29, 2005, Perma-Fix Environmental Services, Inc. (the "Company"),
entered into an amendment ("Amendment") to its Revolving Credit, Term Loan and
Security Agreement ("Agreement") with PNC Bank, National Association ("PNC").
Pursuant to the Amendment, PNC has increased our Term Loan by approximately $4.4
million, resulting in a new Term Loan of $7 million. Under the Amendment, the
Term Loan continues to be payable in monthly installments equal to approximately
$83,333, plus accrued interest, and the remaining unpaid principal balance of
the Term Loan, plus unpaid and accrued interest, being due and payable at the
end of the term of the Agreement. As part of the Amendment, certain subsidiaries
of the Company have modified or granted PNC mortgages to their facilities, in
addition to the collateral previously granted to PNC under the Agreement. The
$18 million revolving credit facility provided to the Company under the
Agreement, together with other terms and conditions to the Agreement, remain
principally unchanged. The term of the Agreement, as amended, terminates in May,
2008, and upon expiration of the term of the Agreement the unpaid principal
balance of the Term Loan and the revolving credit facility, plus accrued and
unpaid interest, shall be due and payable. The Company has used the additional
loan proceeds under the Term Loan to prepay a $3.5 million unsecured promissory
note, which was due and payable in August 2005, and the balance will be used as
general working capital.
