The unique gamma-neutron personal radiation detectors for the search and detection of the radioactive and nuclear materials including nuclear weapons. The detectors measure simultaneously gamma and neutron radiation levels and alert a user if the radiation levels exceed the preset thresholds.
Polimaster gamma-neutron personal radiation detectors PM1703GN are designed to detect the slightest amounts of the gamma and neutron radiation emitting materials. The instruments are equipped with a CsI(Tl) (for gamma detection) and a LiI(Eu) (for neutron detection) scintillation detectors to alert the user that the radiation levels have exceeded the preset threshold values.
The PM1703GN perform 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 instruments non-volatile memory;
Transmit all recorded data to a PC via IR channel for the data processing and analysis.
Once the detector is turned on, it automatically starts taking measurements and storing the background radiation information. The personal radiation detectors PM1703GN can detect even the slightest increase in radiation environment that causes the radiation levels to exceed the preset thresholds. The instruments advanced processing algorithm enables the user to update the background levels and setup the alarm thresholds thus adjusting to the specific radiation environments and satisfy the requirements for the false alarm rate.
