Abstract
The fission track registration efficiency (K wet) of the Garware polyester track (GPF) detector in solution has been determined with respect to the Lexan detector whose K wet is very well known in the literature. The K wet is found to be (1.2 ± 0.1) 10−3 cm. The track registration efficiency of the GPF detector in solution is better than the efficiencies of other nuclear track detectors reported in the literature. This implies that the threshold energies for track registration are different for different detectors and that GPF detector has a lower threshold-energy value. The effects of gamma irradiation in the dose range of 5–51 Mrad on the fission track registration efficiency (K wet) of this track detector from the solution medium are also investigated. The results show that the K wet values for the gamma-irradiated detectors in the above dose range in 2M HNO3 solution medium decreases by ∼7–15%. The changes induced in the gamma-irradiated detectors as a function of gamma dose have also been studied by bulk-etch rate measurements.
