Description
Overview
GAOTek portable radiation survey meter is the only hand-held radiation survey meter designed for detection of neutron and gamma radiation at the same time in China. Its neutron detector and gamma detector are 6LiI (Eu) and CsI (Tl) scintillation crystals coupled with photodiode respectively. The neutron detector is surrounded by a unique cylindrical moderator which greatly improves the sensitivity of neutron detection.
Features
- High sensitivity and fast response
- Neutron/Gamma independent channels
- Durable, compact, user friendly
- High-definition colorful LCD
- Audible and visible alarm simultaneously
- Electro-magnetic interference immunity, CE compliant
- ANSI N42.35 and ITRAP standard compliant
