 The gamma-neutron personal radiation detectors allow searching and detecting radioactive and nuclear materials including weapon grade materials. The detectors have a hermetic and shockproof case and are ideal for operation in the unfavorable and/or harsh environment.

Polimaster gamma-neutron personal radiation detector PM1401GNA is designed to detect the slightest amounts of the gamma and neutron radiation emitting materials especially in the extreme environment and the difficult-to-access areas. The optional telescopic extension tube can be used to protect the user from the radiation sources and/or inspect difficult-to-access areas. The instrument is equipped with a CsI(Tl) scintillation detector for detection of the gamma irradiation and a He-3 detector for detection of the neutron irradiation. The detector will alert the user if the radiation levels exceed the preset threshold values.
The PM1401GNA performs the following functions:
Detect gamma and neutron radiation sources, even if they are shielded;
Search for and locate the gamma or neutron radiation sources including nuclear weapons materials;
Alert the user of the presence of a radiation source through audible, visual and vibrating alarms;
Record and store data for up to 1000 events in the instrument non-volatile memory;
Transmit all recorded data to a PC via IR channel for the data processing and analysis.
