What is the NCRP-recommended annual dose limit for the lens of the eyes?

• A. 100 mSv
• B. 150 mSv
• C. 200 mSv
• D. 500 mSv

Answer: (B)

The recommended annual dose limit for the lens of the eyes, as set forth by the National Council on Radiation Protection and Measurements (NCRP), is 150 mSv. This limit is in place to protect individuals from the potential adverse effects of ionizing radiation, which can lead to cataract formation and other eye-related issues over time. Eye lens exposure is particularly sensitive to radiation, and setting a specific dose limit helps ensure that medical personnel, patients, and others minimizing their risk while still allowing for necessary imaging procedures to be performed.

The guideline establishes a clear threshold to prevent excessive exposure and promotes best practices in radiological safety. It emphasizes the importance of monitoring and managing radiation exposure, especially in occupations where eye exposure is a concern, such as in radiology and certain medical imaging fields. Thus, this standard reflects the ongoing commitment to occupational health and safety in radiation-related professions.
