What is the federal annual dose limit for the skin?

Explanation:
Different tissues have different annual dose limits, reflecting how they respond to radiation. The skin is protected with a higher limit because exposure is often localized and can be managed with shielding and spacing, so the standard allows up to 50 rem per year for occupational skin exposure. This is about 0.5 sievert. By contrast, the whole body limit is much lower (5 rem per year) and the lens of the eye is 15 rem per year, highlighting how sensitive some tissues are to radiation. These values apply to workers; public exposure limits are different. So the skin limit of 50 rem per year is the one that fits.
