Abstract

PM-355 super grade nuclear track detectors were exposed to high gamma absorbed doses up to 5 × 10⁵ Gy (50 Mrad), with an incremental dose of 2.5 × 10⁴ Gy, from a 9.03 PBq (244 kCi) Co-60 source. Results indicate that each of the bulk etch rate (V_b), the track etch rate (V_t) and the sensitivity (V) of the detectors increases with the high gamma absorbed dose, but there is a drop in these parameters at the low gamma absorbed dose. The V_b's for all gamma absorbed doses decreased while their V_t's and V increased with increasing etching time. Signs of surface roughness were observed by increasing the gamma absorbed doses and changes in color observed for doses larger than 2 × 10⁵ Gy. The temperature of the detectors during irradiation reached 40°C. The fission fragment tracks (from a Cf-252 source) disappeared quickly within the etching time (minutes), for total absorbed doses greater than 3 × 10⁵ Gy, due to their high bulk etch rate.
