Gamma dosimeter AТ2533

X-rayradiation

Measurement of ambient dose equivalent rate and ambient dose equivalent of continuous X-ray and gamma radiation in an extremely wide range and under harsh operating conditions, including emergency response. Measurement of pulsed radiation dose and average dose rate directly at linear accelerators (LINACs) and other pulsed-radiation facilities. High burn-up life, rugged construction and integrity of detection unit Measurement in liquids at depths up to 40 m User friendly and easy to operate, highly available and can be used in gloves Instrument-to-PC data exchange over USB or Bluetooth interface (АТ2533/1) The PU is able to control the radiation situation at operator location Detector Silicon semiconductor detector; Geiger-Muller counter tube Energy range 50 keV – 10 MeV Measurement range of ambient dose equivalent rate Ḣ*(10) 1 µSv/h – 1000 Sv/h Measurement range of ambient dose equivalent Н*(10) 10 µSv – 5000 Sv Limits of variation of the response due to dose Н*(10) and dose rate Н*(10) ±15% Measurement range of average pulsed radiation dose rate 30 µSv/s – 0.3 Sv/s (100 mSv/h – 1000 Sv/h) (pulse repetition rate is not less than 20 cps, duration not less than 1 μs) Measurement range of pulsed radiation dose 10 µSv – 5000 Sv Limits of variation of the response due to dose and average dose rate of pulsed radiation ±20% Limits of variation of relative response due to gamma radiation energy (50 keV to 3 MeV) and angle of incidence (0° to ±45°) -29% to +67% Typical sensitivity to 137Cs gamma radiation 0.15 cps/(µSv·h-1) (for Ḣ*(10) ≤0.1 Sv/h) 58 mV/(Sv·h-1) (for Ḣ*(10) >0.1 Sv/h) Response time for 10-fold dose rate change ≤10 s (for Ḣ*(10) >10 µSv/h)
