How should radioactive sources be stored when not in use?

Radioactive sources should be stored in a secure and shielded container to ensure safety and compliance with regulations. This method minimizes the risk of exposure to radiation for personnel who may be nearby. A properly designed container will protect both the environment and surrounding individuals from harmful radiation emissions. Shielding is critical because it absorbs or deflects radiation, reducing the dose that could potentially affect workers or the public.

Storing radioactive materials in a secure manner also deters unauthorized access, thus preventing any potential misuse or accidents. Regulations surrounding the storage of radioactive sources are strict, emphasizing the importance of both security and the use of shielding materials to protect against radiation hazards.

In contrast, storing radioactive sources in an open area would expose them to unnecessary risks, including environmental factors and unauthorized access. Keeping them in a refrigerator does not address the need for protection against radiation and could complicate handling and access during use. Using a workshop for easy access may increase the likelihood of accidents and does not provide the necessary shielding or security for the radioactive materials.
