Final answer:
The established annual occupational dose-equivalent limit for the lens of the eye is 150 millisieverts (mSv) to protect against radiation-induced cataracts and is enforced to ensure safety standards in workplaces with potential radiation exposure.
Step-by-step explanation:
Occupational Dose Limit for the Lens of the Eye
The established annual occupational dose-equivalent limit for the lens of the eye is specifically set to protect workers from ocular radiation exposure that could result in cataracts. According to the International Commission on Radiological Protection (ICRP) and regulated by various national agencies, this limit is generally recommended to be 150 millisieverts (mSv) per year for occupational exposure to protect against radiation-induced cataracts. Workers in various fields such as medical, nuclear, and industrial environments, where exposure to ionizing radiation can be a concern, must adhere to these standards to minimize the risk of damage to the lens of the eye and maintain long-term ocular health.
The lens of the eye is particularly sensitive to radiation, and excessive exposure can lead to conditions such as cataracts, which is why specific limits are set. These limits are important aspects of the work environment in occupations where radiation exposure is possible, ensuring that safety standards are maintained to protect employees' health. Adequate protection, monitoring, and adhering to such guidelines are crucial in maintaining safe occupational health practices.
