Radiation dose measuring device. The device detects surface contamination from alpha and beta radiation, and monitors the dose rate of X rays and gamma rays. Equipped with a large LCD display, it relies on a built - in high - speed microprocessor as its data processing unit. Temperature range 40C to 50C. Measuring range count rate 0 - 500000 CPM, 0 - 8000 CPS dose rate 0.01 - 10000 Sv/ h10 mSv/ h Measurement
