What is the purpose of "Radiation Warning Signs"?

The purpose of "Radiation Warning Signs" is primarily to alert personnel to the presence of radiation hazards. These signs serve as crucial indicators that radiation levels may pose a risk to individuals in the vicinity. By clearly marking areas where radiation is present, these signs help ensure that personnel are aware of potential exposure risks and can take appropriate precautions when entering or working in those areas. This is a fundamental element of radiation safety protocols, aimed at protecting individuals from the harmful effects of radiation exposure.

While other options mention important aspects related to radiation safety, they do not capture the main function of these warning signs. For example, indicating restricted areas is a part of radiation safety procedures but is not the primary purpose of the signs themselves. Similarly, promoting safety training is essential for overall safety but is not the direct function of a radiation warning sign. Lastly, marking the location of radiation sources relates to management of the environment rather than directly communicating the hazards present, which is the primary focus of the warning signs.
