High quality Geiger Counter for detecting all Nuclear Radiation, Gamma, Beta and X=Rays. Also detects Radon, Iodine 131, Iodine 125 , Am 241 and other radioactive substances. Ihe natural environment there is background radiation, real-time data will fluctuate within a certain range.Use the PROtastic Dosimeter to help to warn and avoid against radiation hazards in everyday life. Our Geiger Counter uses a sophisticated military grade Geiger-Muller tube as the core sensor. This give higher sensitivity, a longer life and a wide measuring range. The audio can be muted or set to 'alarm mode' and the screen can be turned off to save batteries. 3xAA batteries required. Alternatively, use rechargeable batteries (not included) and charge with a mini USB cable (not included).
