Atomic Energy Aims and scope

Abstract

The main objective of this work is to study experimentally the range and number distribution of 235U fission fragments over the thickness of thin lavsan films. A BR-10 reactor was used to irradiate a stack of lavsan films and the first experimental determination of the differential distribution of the number of 235U fission fragments over the film thickness is made. The results obtained are compared with the average values computed with the SRIM-2000 computer code. It is shown that the SRIM-2000 program makes it possible to describe satisfactorily the experimental data on the interaction of fission fragments with polymers. The data obtained are used as a basis to determine the optimal thickness of a polymer film for producing track membranes by the reactor method.
