Gamma Radiation Detector BDG3 for PM1403
Gamma radiation detector BDG3 performs the following functions: measurement of dose equivalent rate (DER) of X-ray and gamma radiation, search for the photon radiation sources, registration and accumulation of photon radiation scintillation spectra.
BDG3 can be used by emergency services, radiological and isotope laboratories, customs and border services, nuclear industry facilities, to search, detect and localize radioactive and nuclear sources and prevent illicit trafficking of radioactive and nuclear materials.
Operation Principle
BDG3 is connected to the Spectroscopic Radiation Monitor PM1403, Display and Control Unit РМ1403 and Display and Control Unit РМ1403-01 or a PC via RS-485 or USB. Operation algorithm enables continuous measurement process, processing of the measurement results and quick adaptation to radiation intensity changes. In the programming mode BDG3 enables recording of data into the non-volatile memory, continuous control over the DER threshold level, sound/visual alarm if the set DER level is detected or exceeded.
Operating Mode
The BDG3 operates in the following modes:
DER measurement of photon radiation
search for the photon radiation sources
registration and accumulation of the photon radiation scintillation spectra
identification of the radionuclide matter composition
programming of the operation modes

Dosimeters perform monitoring and measurement of personal dose equivalent and personal dose equivalent rate in the wide energy range – from the natural background level up to 5-10 Sv/h (500-1000 R/h). Instruments are stable to dose up to 300 Sv, have two thresholds in DER and DE ranges, have non volatile memory for data storage. Hermetic, water-resistant and shockproof case and the fluorescent backlight on LCD screen allow to use instruments in harsh and extreme conditions.
PM1604A and PM1604B dosimeters are recommended for emergency services, customs and border patrol, radiological and radioisotope laboratories, medical professionals, personnel of nuclear facilities, civil defense, firefighters and police.
