What is the recommended annual lens of the eye effective dose limit for occupationally exposed individuals?

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

Answer: (C)

The recommended annual lens of the eye effective dose limit for occupationally exposed individuals is set at 150 mSv. This limit is established by organizations such as the International Commission on Radiological Protection (ICRP) and is designed to protect workers in fields that involve exposure to ionizing radiation, such as radiography and other medical imaging professions.

The reasoning behind the specific limit of 150 mSv is based on research about the potential harmful effects of radiation on the eye, particularly regarding cataract development. Evidence suggests that exposure to radiation above this threshold can significantly increase the likelihood of cataractogenesis, making it essential to establish a dose limit that balances the need for radiation use in medical settings with the responsibility to protect the health and safety of workers.

The choice of this limit also reflects a precautionary approach in radiation safety, ensuring that occupational exposure remains within levels that promote the well-being of healthcare professionals while still allowing them to perform their necessary duties.
