RESPONSE OF SOLID DIELECTRICS TO THE REGISTRATION OF FISSION-PRODUCT TRACKS

Fission products emitted from Cf-252 source have been registered in Tr iafol-TN, Triafol-BN, SR-86(20) and ZnP-glass detectors. The latent da mage trails created by these fission products have been chemically dev eloped under suitable conditions. Detectors have been characterised in terms of etching isotropy, critical etch parameters and maximum etcha ble track lengths. The most probable track lengths have been compared with the theoretically computed values from codes RF and TRIM. Identif ication of the fission products was done from the experimental values of the maximum etchable track lengths and the theoretical ranges obtai ned with the computer program 'FFR'.
