What is the annual occupational dose limit to the eye according to NRC regulations?

• A. 100 mSv
• B. 200 mSv
• C. 150 mSv
• D. 50 mSv

Answer: (C)

The correct answer reflects that the annual occupational dose limit to the eye is indeed 150 mSv, as established by NRC regulations. This limit is specifically designed to protect workers in environments where they may be exposed to ionizing radiation, such as in nuclear medicine, radiology, and other fields involving radiation use. In setting this limit, regulatory agencies such as the NRC consider the potential health risks associated with radiation exposure, particularly to sensitive tissues such as the lens of the eye. The specified limit aims to minimize the risk of cataract formation, which can be a long-term consequence of excessive radiation exposure. Other dose limits, while higher, do not apply specifically to the eye and are set for different tissues or organs, emphasizing the special consideration given to ocular safety in radiation work. Thus, knowing the specific limit of 150 mSv is crucial for professionals in managing their exposure and ensuring compliance with health and safety regulations.
