What is the annual occupational dose equivalent limit for the lens of the eye according to 10 CFR 20?

The annual occupational dose equivalent limit for the lens of the eye is set at 15 rem or 0.15 Sv according to 10 CFR 20. This standard has been established by the National Council on Radiation Protection & Measurements (NCRP) and adopted in federal regulations to protect workers from the potential harmful effects of ionizing radiation, particularly to sensitive tissues such as the lenses of the eyes.

The determination of this limit is based on research concerning radiation exposure and the correlation to the risk of developing cataracts and other ocular health issues. By establishing a specific limit for the lens of the eye, regulatory agencies aim to ensure that individuals who work in environments where radiation is present can do so safely, while minimizing the risk of radiation-induced damage.

Other options suggest limits that do not align with current regulations, which underscores the importance of adhering to the specific guidelines set forth in 10 CFR 20 for the protection of radiation workers.
