1. Geiger counter nuclear radiation detector is an ionizing radiation detector, which is mainly used to detect nuclear radiation such as -rays, gamma-rays and X-rays in the environment. 2. This detector has the function of a personal dosimeter, which can accurately measure the radiation dose of an individual in a radiation environment and protect the radiation safety of personnel. 3. The marble detector is designed with high-sensitivity materials, which can effectively detect radiation sources and provide accurate radiation data, which is helpful for judging the radiation level of the environment. 4. With the help of the LCD display of the -gamma X-ray tester, users can visually view the current radiation data and dose levels, which is convenient for real-time monitoring of radiation conditions. 5. This detector is easy to carry and is suitable for radiation monitoring in nuclear power stations, radiation laboratories, medical institutions and other places, aiming to ensure the radiation protection and safety of workers and the public.
