Final answer:
The lifetime occupational dose limit to the whole body of an occupationally exposed person who is 52 years old is determined by the International Commission on Radiological Protection (ICRP). According to the ICRP, the annual effective dose limit for occupational exposure is 20 mSv averaged over 5 years, with a cumulative dose limit of 100 mSv at any age. To calculate the cumulative dose, we can consider the average annual limit and multiply it by the number of years the person has been exposed.
Step-by-step explanation:
The lifetime occupational dose limit to the whole body of an occupationally exposed person who is 52 years old is determined by the International Commission on Radiological Protection (ICRP). According to the ICRP, the annual effective dose limit for occupational exposure is 20 millisieverts (mSv) averaged over 5 years, with a cumulative dose limit of 100 mSv at any age.
Since the question asks for the lifetime occupational dose limit, we can assume that the person has been exposed to radiation throughout their career. If they are 52 years old, it means they have likely been working for several years. To calculate the cumulative dose, we can consider the average annual limit of 20 mSv and multiply it by the number of years the person has been exposed. For example, if the person has been exposed for 20 years, the cumulative dose would be 20 mSv/year x 20 years = 400 mSv.
It's important to note that the dose limits are set to ensure the health and safety of occupationally exposed persons, and they take into account the potential risks associated with radiation exposure. These limits are regularly reviewed and updated based on scientific research and advancements in radiation protection.
