Radiometer neutron and gamma radiation RKS-02 "cordon"
|
The radiometer neutron and gamma radiation RKS-02 "Kordon" (the radiometer) is used to rapidly identify authorized and unauthorized import and export of sources of neutron and gamma radiation or radioactive contaminated vehicles or cargo to transport communications; to control unauthorized bring (import) of radiation sources (or materials contaminated with radioactive substances) during the passage through the reference space personnel at the entrance (or exit) the territory of industrial plants and objects of national importance, etc.
The radiometer is a stationary unit, consisting of a detection and measurement block units with integrated power supply.
detection unit converts the total flux of neutron and gamma radiation in a sequence of pulses at the output. The principle of operation detection units based on the scintillation plastic scintillator. As used plastic scintillator detector, which is sensitive to gamma and neutron radiation. The counting rate of the output sequence of pulses is proportional to the density of the total flux of gamma rays and neutrons in the location detecting unit.

When "absolute" threshold radiometer responds to exceeding of the total radiation level from the background and from the controlled object; time measurement values are set from 0.125 to 128 seconds.. The detection efficiency radiometer gamma rays and fast neutrons from the source corresponds PuBe values (with a deviation of no more than ± 35%) given in the table.
