Survey meter for gamma ray and X-ray

AT1121

Detector Scintillation plastic, Ø30×15 mm

Measurement range of ambient dose equivalent rate:
– Continuous radiation: 50 nSv/h – 10 Sv/h
– Short-term radiation: 5 µSv/h – 10 Sv/h
– Pulse radiation: 0.1 µSv/h – 10 Sv/h (АТ1123)

Measurement range of ambient dose equivalent 0.1 nSv – 100 Sv

Energy range:
– Continuous and short-term radiation: 15 keV – 10 MeV
– Pulse radiation: 15 keV – 10 MeV (АТ1123)

Energy dependence relative to 662 keV (137Cs)
±35% (15 – 60 keV)
±25% (60 keV – 3 MeV)
±50% (3 – 10 MeV)

Measurement time of 137Cs gamma radiation dose rate
– Dose rate: 50 – 300 nSv/h ≤60 s
– Dose rate: 0.3 – 2 µSv/h ≤10 s
– Dose rate: 2 µSv/h – 10 Sv/h ≤2 s

Response time for dose rate change from 0.1 to 1 µSv/h <2 s

Typical sensitivity to 137Cs gamma radiation 70 cps/(µSv·h-1)
