Gamma-Neutron PRDs
Gamma-neutron personal radiation detectors PM1401GNM are designed to detect the slightest amounts of gamma and neutron radioactive materials in harsh environmental conditions and difficult-to-access areas. Instruments are lightweight, have hermetic and shockproof case, non-volatile memory for data storage, small size and user-friendly interface.
