What is the annual equivalent dose limit (AEQDL) to the lens of the eye?

The annual equivalent dose limit (AEQDL) to the lens of the eye is established at 150 mSv. This limit is set by regulatory organizations such as the International Commission on Radiological Protection (ICRP) and is based on research indicating that exposure to ionizing radiation can significantly impact the clarity of the lens, potentially leading to cataract formation.

The lens of the eye is particularly sensitive to radiation, and the established dose limit reflects a balance between occupational exposure and the protection of health care workers and patients during diagnostic and therapeutic procedures. The higher limit compared to other organs acknowledges the unique risks associated with radiation exposure to the eyes, ensuring appropriate safety measures and monitoring are in place for individuals particularly at risk in clinical settings, such as those working in radiology or radiation therapy.
