摘要：

We determine the behavior of track etch rate V(T) along the tracks in CR-39 detectors exposed to fission fragments from (252)Cf source. CR-39 detectors are etched at 70 degrees C in different concentrations of Na(2)CO(3)-mixed 6M NaOH solutions for different etching time intervals of 5-10 min starting from 15 min up to 210 min. Two values of track etch rate are determined along the fission fragment trajectories. The variation in V(T) is correlated with the energy loss rate of the fission fragment in the detector material.
