Description
Overview
GAOTek gamma radiation survey meter is the only handheld radiation survey meter designed for detection of neutron and gamma radiation at the same time in China. Its neutron detector and gamma detector are 6 liI (Eu) and CsI (Tl) scintillation crystal coupled with photodiode respectively. The neutron detector is surrounded by a unique cylindrical moderator which greatly improves the sensitivity of neutron detection.
