Neutron gamma dosimeter comprises at least three channels, for detecting slow neutrons, fast neutrons and gamma radiation.

摘要

A neutron gamma dosimeter for detecting thermal neutrons, fast neutrons and gamma radiation using semiconductor detectors, comprises at least three channels. One channel has a detector for gamma radiation (1A), and the other two channels have a detector for thermal neutrons (1B) and fast neutrons (1C). The channel for gamma radiation detection has an adjustable barrier potential which enables sensitivity to be adjusted.
