Fast neutron detection in CR-39 and DAM-ADC nuclear track detectors.

Abstract

Fast detection of neutron in CR-39 and DAM-ADC nuclear track detectors were investigated using new etching conditions. The neutron irradiation is performed using a 5 mCi Am-Be source present at the National Institute of Standards (NIS) of Egypt. Using the new etching condition, irradiated CR-39 samples were etching for 4h and DAM-ADC samples for 80 min. Suitable analyzing software has been used to analyze experimental data. The dependence of neutron track density on the neutron fluence is investigated. When etching under optimum conditions, the relation between track density and fluence is determined which is found to be linear. Detection efficiency has been represented for both SSNTD, and found to be constant with fluence, which reflects the importance of using CR-39 and DAM-ADC detectors in the field of neutron dosimetry. linear relationship between track density and effective dose is determined.
