Nuclear radiation refers to the radiation emitted by radioactive substances in nature or human activities, which has a certain degree of harm to human health and the environment. In order to monitor and control the level of nuclear radiation, scientists have invented a nuclear radiation testing instrument. Nuclear radiation testers are devices that use ionization, excitation effects, or other physical and chemical changes caused by radiation in gases, liquids, or solids for radiation detection. They are widely used in fields such as nuclear energy, healthcare, and environmental protection. The following ATO industrial automation will introduce the working principle and usage methods of nuclear radiation testing equipment to help everyone use and understand it correctly.
