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

Typical non-radioactive radiation sources are various types of electrical 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 cease.

Radioactive radiation sources (or simply radioactive sources) contain radioactive substances, that is, substances composed of radioactive elements that emit radiation on their own (the so-called radioactive elements). A radioactive source never stops emitting radiation, but the intensity of the radiation decreases over time. Half-life refers to the time at which radioactivity is reduced to half due to radioactive decay. For example, since the half-life of cesium 137 is about 30 years, the intensity of the radiation source is reduced by half every 30 years.
