Gamma Radiation Detector Detection BDG2 performs the following functions when connected to the Spectroscopic Radiation Monitor РМ1403: indication of the measured value of DER and DE of gamma radiation; indication of average count rate and measured DER value; programming of BDG2 operation modes.
BDG2 can be used by radiological and isotope tracing laboratories, customs officers, emergency services to search and detect ionizing radiation sources.
Operation Principle
Geiger-Muller counter is used to measure DER and DE of photon radiation. Operation algorithm enables continuous measurement process, processing of the results and quick adaptation to radiation intensity changes. BDG2 in the programming mode enables recording data into non-volatile memory and continuous control over two DER and DE threshold values, as well as sound and light alarming when set thresholds are exceeded.
Operating Mode
When the instrument is connected to the Spectroscopic Radiation Monitor РМ1403 / Display and Control Unit РМ1403 / Display and Control Unit РМ1403-01 or PC it enables reading from BDG2:
- DER and DE measurement data
- DER measurement statistical error
- DE accumulation time
- BDG2 number
- DER and DE threshold levels values
- sound alarm state (On/Off)
Recording into BDG2 the following information:
- DER and DE threshold levels values
- command of accumulated DE and DE
- accumulation time resetting
- command sound alarm "On/Off"
