What is the recommended cumulative whole-body EDE limit?

A. Age in years multiplied by 1 Sv (100 rem)
B. Age in years multiplied by 10 Sv (1000 rem)
C. Age in years multiplied by 1 mSv (100 mrem)
D. Age in years multiplied by 10 mSv (1000 mrem)

Answer :

Final answer:

The recommended cumulative whole-body EDE limit is typically equivalent to a person's age in years multiplied by 1 mSv (100 mrem) or the 10 mSv rule. This standard focuses on limiting an individual's lifetime exposure to radiation. The correct option is C.

Explanation:

The recommended cumulative whole-body Effective Dose Equivalent (EDE) limit for those routinely working with radiation is 'age in years multiplied by 1 mSv (100 mrem)'. This rule is referred to as the '10 mSv rule'. Essentially, the cumulative whole-body dose limit (in mSv) should not exceed the person's age (in years), hence, having a focus on a person's 'lifetime radiation dose'.

For example, if an individual is 30 years old, their cumulative dose for their entire lifetime, including background exposure, should not exceed 30 mSv.
