AT6102, AT6102A, AT6102B Spectrometers

Portable multifunctional radiation monitoring devices, primarily designed for search and detection of gamma radiation sources with automatic identification of radionuclide composition.

Can be used for area and land radiation monitoring with data GPS-referencing. АТ6102 model can detect neutron radiation and measure neutron count rate.
Operating principle

The spectrometer operates in continuous radiation environment scan mode: search, detection, localization and identification of gamma sources; detection of neutron radiation.
When radioactive source is detected the spectrometer activates alarm and identifies its radionuclide composition.
High-sensitivity scintillation NaI(Tl) gamma radaition detector is used in these devices. The spectrometer is equipped with Geiger-Muller counter with filter, which aligns energy dependence of appliance sensitivity to extend dose rate measurement range.
Two integrated proportional helium counters of slow neutrons in polyethylene moderator are used in АТ6102 model.
The possibility of external detection unit connection allows measurement of alpha and beta particles flux density from contaminated surfaces (BDPA‑01/ BDPB‑01) andneutronradiationdoserate(BDKN‑03).
