What is the occupational exposure limit for skin/extremities in terms of Sieverts per year?

The occupational exposure limit for skin and extremities is defined as 0.5 Sv (Sieverts) per year. This limit is established to ensure that individuals working in environments where they could be exposed to radiation, such as in nuclear medicine or radiology, are not at risk of adverse health effects due to excessive radiation exposure.

The value of 0.5 Sv reflects research and guidelines established by organizations such as the International Commission on Radiological Protection (ICRP) and regulatory bodies focused on worker safety. This standard aims to balance the necessity of occupational exposure in medical and industrial applications with the objective of protecting the workers' health.

Lower limits provided in the other choices generally pertain to whole-body exposure limits or other specific contexts but do not apply to the limits set for skin and extremities. Therefore, the choice of 0.5 Sv aligns accurately with established safety protocols for occupational radiation exposure.
