    • Abstract

       

      An attempt is made to determine the response of CR-39 and cellulose nitrate plastic track detectors subjected to thermal neutrons. The α-particles are produced from (n, α) reactions in lithium tetraborate convertor placed in contact with different plastics and are recorded in the detectors. The corrected track density gives a fluence sensitivity and dose sensitivity of the order of 10−4 tracks per neutron and 102 tracks/cm2 mrem respectively. A linear relationship is observed between track density and neutron fluence.
