What is the annual dose limit for the lens of the eye for an occupational worker?

The annual dose limit for the lens of the eye for an occupational worker is set at 50 mSv (5 rem). This limit is established by radiation protection guidelines to help prevent radiation-induced cataracts, which are a significant risk associated with high doses of ionizing radiation to the eye.

The rationale for this specific limit is based on scientific studies that have demonstrated a correlation between radiation exposure to the lens and the occurrence of cataracts. Regulatory agencies, such as the International Commission on Radiological Protection (ICRP) and the U.S. Nuclear Regulatory Commission (NRC), have established this limit to provide a balance between allowing workers to perform their duties while minimizing risks to their health.

In contrast, other dose limits for various body parts and the whole body are different. Knowing these distinctions is crucial for professionals in the field to ensure they adhere to safety protocols and protect themselves from potential long-term effects of radiation exposure.
