Abstract

A new nuclear track detector, called SR-90, has been compared with two types of CR-39 nuclear track detectors (i) super grade PM-355 Pershore Mouldings/U.K. and (ii) MA-ND/α/Hungary. All types were irradiated with alpha and fission fragments and all etched under the same etching conditions. The bulk etching rate (V_b) of SR-90 was twice that of the CR-39 for all etching times. The track etching rate (V_t) of SR-90 starts with 8.5 μm.h^-1 at 2 h etching time and increased to 13 μm.h^-1 at 6.5 h, while for CR-39 remains nearly constant (2 μm.h^-1) for all etching time. Thus, the sensitivity of SR-90 was found to improve with etching time. The surface of SR-90 is found to be rough and less transparent than both types of CR-39 detectors. The shape of perpendicular alpha and fission fragment tracks in SR-90 was not a uniform circular shape as in the CR-39.
