X-Ray and Gamma Radiation Monitor – Dosimeter AT1121-AT1123

The primary function of these dosimeters is the X-ray and gamma radiation dosimetry in wide ranges of ambient dose equivalent rate and energy. Additional functions are the detection of sources of soft and hard gamma radiation, beta emitters, measurement of pulsed and short-term radiation with exposure time estimation, as well as measurement of moving sources of radiation.
