Gamma Radiation Detector BD-03 (for PM1402M)
A portable multipurpose radiation laboratory PM1402M is consists of a processing unit and five external exchangeable radiation detectors. PM1402M can be used for detection and measurement of alpha, beta, gamma and neutron radiation and gamma spectrum accumulation.
Gamma Radiation Detector BD-03 is based on GM-counter and designed for measurement of ambient equivalent dose rate of X-ray and gamma radiation.
Operation Principle
Gamma Radiation Detector BD-03 is equipped with Geiger-Mueller counter and enables measurement of ambient equivalent dose rate of X-ray and gamma radiation.
Detectors Full Set
Gamma Radiation Detector BD-01 – based on CsI(Tl) detector, enables search of gamma radiation sources
Gamma Radiation Detector BD-02 – based on CsI(Tl) detector, enables search and measurement of gamma radiation sources and spectrum accumulation
Gamma Radiation Detector BD-03 – based on GM-counter, enables measurement of ambient equivalent dose rate of X-ray and gamma radiation
Neutron Radiation Detector BD-04 – based on H-3, enables search and location of the neutron radiation sources
Alpha and Beta Radiation Detector BD-05 – enables evaluation of alpha and beta contamination levels
