What is the maximum permissible dose of radiation exposure for non-radiation workers per year according to NRC guidelines?

The correct choice regarding the maximum permissible dose of radiation exposure for non-radiation workers per year, according to NRC guidelines, is indeed 1 mSv. This standard is established to protect the health and safety of individuals who are not employed in radiation-related fields and who may still be exposed to low levels of radiation in their environment or through incidental exposure.

The 1 mSv limit is justified based on a careful assessment of risks versus benefits, considering the potential health effects of ionizing radiation, particularly the increased risk of cancer over a lifetime. The NRC aims to minimize exposure to these individuals while still acknowledging that some level of radiation exposure can occur from natural and artificial sources in the environment.

This standard reflects a commitment to maintaining public safety and minimizing unnecessary exposure, ensuring that non-radiation workers remain within safe limits while allowing for the practical considerations of their environments. It is essential for radiation safety protocols to comply with these guidelines, fostering a culture of safety and accountability in all settings where radiation may be present.
