Abstract
The construction of a dosimeter for measuring the ambient dose of neutrons with energy from 10–4 MeV to 1 GeV based on a cylindrical polyethylene moderator with lead and cadmium inserts and a 3He counter of thermal neutrons is proposed. Numerical Monte Carlo simulations based on the GEANT4 and SHIELD programs were applied to choose the optimal design of the dosimeter and calculate its energy sensitivity function. The device can be used for operational and stationary radiation monitoring in neutron fields on high-energy accelerators. A comparison of the dosimeter characteristics with foreign analogs is given.
