[0002] Radioactive source detection refers to the safety detection of radioactive substances that can generate ionizing radiation or electromagnetic radiation, etc. Ionizing radiation is usually also called radioactive radiation. Since the energy generated by this kind of radiation is relatively high and can cause the ionization of atoms of surrounding substances, it is called ionizing radiation. Electromagnetic radiation is the radiation generated by electromagnetic waves generated by alternating electric and magnetic fields to the surrounding space. Due to the great harm of radioactivity and the fact that it generally must be detected by special instruments, radioactive detection is widely used in production and life.
