Desktop plastic scintillator detector as a potential single replacement for both neutron and Gamma-ray detectors

Abstract

This work is based on the design introduced by the cosmic watch project from the Massachusetts Institute of Technology has been constructed and compromised to be used for radiation detection and dosimetry applications. This single detector is a potential replacement for neutron and gamma-ray detectors in radiation portal monitors (RPM) systems. Non-linear dose-response of this detector while exposure to gamma dose rate in the μGy/hr range is obtained while linear count rate is obtained for exposure to the neutron flux. Neutron flux distribution around the Am-Be neutron source, neutron security gating, and gamma dosimetry are three successful applications checked in this study. The obtained results recommend using this plastic scintillator as a potential single-detector replacement for both neutron and gamma-ray detectors in radiation portal monitors (RPM) systems.
