What is the annual dose equivalent limit for the lens of the eye for occupational workers?

The correct answer for the annual dose equivalent limit for the lens of the eye for occupational workers is 150 millisieverts (mSv). This limit is established based on guidelines from organizations such as the International Commission on Radiological Protection (ICRP) and the National Council on Radiation Protection and Measurements (NCRP), which focus on protecting workers from potential radiation-induced effects.

The lens of the eye is particularly sensitive to ionizing radiation, and exceeding the designated limit could increase the risk of cataracts and other radiation-induced damage. The specific limit of 150 mSv reflects a balance between allowing occupational exposure essential for work while ensuring safety and minimizing health risks.

In contrast, higher limits, such as those mentioned in the other options, would pose significantly increased risks to ocular health and do not align with current radiation safety standards. By adhering to established safety guidelines, occupational workers can effectively manage their exposure and maintain a safe working environment.
