What is the dose limit for the lens of the eye for occupational workers as per NCRP 116?

The dose limit for the lens of the eye for occupational workers, as established by the National Council on Radiation Protection and Measurements (NCRP) Report No. 116, is set at 150 millisieverts (mSv). This guideline is in place to protect workers from the potential adverse effects of radiation exposure, particularly cataract formation, which can be a significant risk at higher radiation doses. By enforcing this limit, the NCRP aims to ensure occupational safety and health standards within environments where radiation exposure may occur.

Understanding the importance of this limit is crucial for health and safety in radiological practices, emphasizing the need for protective measures and monitoring dosages to adhere to these guidelines. The other figures provided in the choices do not reflect the established threshold for lens exposure, highlighting the importance of keeping updated with current regulations and standards in the field.
