Abstract
The critical angles of the CR-39 (theta(c)) and LR-115 type II (theta(c)') solid state nuclear track detectors (SSNTD) for detecting alpha-particles e mitted by the uranium and thorium series have been evaluated by calculating the corresponding ranges of the emitted alpha-particles in different mater ial samples and in the SSNTD studied. The influence of the emitted alpha-pa rticles initial and residual energies on the critical angles of the SSNTD s tudied has been investigated. The uranium and thorium contents of different geological samples have been evaluated by exploiting data obtained for the critical angles of the CR-39 and LR-115 type II solid state nuclear track detectors and measuring the corresponding densities of tracks.
