Information

Radiation source refers to a device or substance that can emit or emit ionizing radiation. Some devices may also be sources of radiation that are not necessarily "radioactive".

Typical non-radioactive radiation sources are various types of electric radiation generators, such as X-ray machines and particle accelerators, which emit radiation during operation, but once the power supply is cut off, their radiation characteristics stop.

Radioactive radiation sources (or radioactive sources for short) contain radioactive substances, that is, substances composed of radioactive elements that can emit radiation by themselves (the so-called radioactive elements). The radioactive source never stops emitting radiation, but the radiation intensity declines over time. Half-life refers to the period during which radioactivity is reduced to half due to radioactive decay. For example, because the half-life of cesium-137 is about 30 years, the intensity of the radiation source is reduced by half every 30 years.
