What is the occupational exposure limit for the lens of the eye per year?

The occupational exposure limit for the lens of the eye is established to protect against potential damage from radiation exposure. In this context, the limit is set at 15 rem per year.

This limit is based on scientific studies observing the effects of radiation on human tissues, particularly the lens of the eye, which is particularly sensitive to radiation. High levels of exposure can lead to cataracts and other vision problems. Regulatory bodies, such as the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP), have established this threshold to minimize the risk of such adverse health effects in occupational settings where radiation exposure could occur.

This understanding is vital for professionals working with radioactive materials or in environments where radiation is present, ensuring they adhere to safety guidelines to protect their health over time.
