According to NRC regulations, what is the annual whole body occupational dose limit (TEDE) for adults?

The annual whole body occupational dose limit for adults, as defined by the Nuclear Regulatory Commission (NRC), is indeed 5000 mRem, or 5 Rem. This limit is set to ensure that workers in the nuclear industry are exposed to radiation levels deemed safe for occupational safety, while still allowing them to perform their necessary duties. The NRC regulates exposure to ionizing radiation to protect workers' health, and this limit reflects a balance between potential risks and the operational needs of the industry.

This regulation helps in protecting workers from the potential harmful effects of radiation while recognizing that some exposure is a part of their job. It essentially promotes safe practices and necessary precautions while conducting work that involves radiation, aligning with guidelines set by both federal and international health organizations.

The other options listed are either significantly lower than the established limit or are not in accordance with the NRC's standards for occupational exposure.
