How should background radiation be classified?

Background radiation should be classified as both occupational and environmental exposure because it encompasses a variety of radiation sources that individuals may encounter in their daily lives and work environments.

Environmental exposure includes radiation from natural sources such as cosmic rays, terrestrial radiation from soil and rocks, and radon gas emanating from the ground, which contributes to the radiation dose received by the general public.

On the other hand, occupational exposure refers to the radiation that workers might encounter due to their jobs, especially in industries involving radioactive materials or radiation-producing equipment. This can include additional contributions to their exposure from background sources when they are operating in areas influenced by environmental radiation.

By recognizing background radiation as both occupational and environmental, it allows for a more comprehensive understanding of radiation safety and dose assessment, ensuring that both aspects are considered in protective measures and health regulations. This classification emphasizes the importance of managing both types of exposure in ensuring safety in various environments where radiation is present.
