摘要：

CN-85 cellulose nitrate track detectors irradiated with Cf-252 in 2pi geometry, had undergone post-irradiation thermal annealing and ultraviolet treatments, separately. Diametric measurements of the etched ''through holes'' have been made. Profiles of the pores affected by the post irradiation treatments have been studied. Thermal annealing of the detectors at 98-degrees-C produces ''through holes'' of uniform size and relatively of smaller dimensions as compared to the unannealed and U.V. treated filters. Activation energy of annealing has been found to be (0.12 +/- 0.01) eV.
