Abstract

A recently developed Si detector system that is capable of distinguishing recoil protons from a hydrogen-rich radiator, depending on charged particles generated by /sup 6/Li(n, alpha)T nuclear reaction, is investigated, taking essential requirements for personnel dosimeters into account. This dosimeter is a REM counter based on a new principle. It possesses two different target materials and distinguishes low-energy neutrons from fast neutrons. Results of response measurements for both types of neutrons are presented, and the results are evaluated. It is concluded that this method can be used to make a compact personnel neutron dosimeter with sufficient detection efficiency.<>
