“…Some of these factors are the detector irradiation to electrons (Goland and Mateosian 1973), neutron, UV gamma (Khan 1980, Henke et al 1970, Frank and Benton 1970, De Sorbo 1979, De Sorbo and Humphrey 1970 and laser radiation (Kukreja et al 1984). A number of different SSNTDs have been studied by several workers (Farid 1984, Saxena et al 1987, Somogyi 1972 for their suitability as nuclear track detectors. Of these the Makrofol-N was found to be the most favourable and sensitive to the registration of heavy ions.…”
