What is the cumulative occupational exposure acceptable for a 48-year-old radiographer?

To determine the cumulative occupational exposure acceptable for a radiographer, one can refer to the guidelines established for radiation workers. Specifically, the commonly used formula is 10 mSv multiplied by the worker's age (in years).

For a 48-year-old radiographer, the calculation would be:

Cumulative exposure = 10 mSv × Age

Cumulative exposure = 10 mSv × 48 years

Cumulative exposure = 480 mSv

This figure aligns with the accepted standards set forth by regulatory bodies, which seek to minimize health risks associated with radiation exposure while allowing for necessary occupational limits. The value of 480 mSv is considered a safe guideline for individuals who work in environments with potential exposure to radiation, thus making this option the correct choice.

Other options do not reflect the appropriate calculation based on the age of the radiographer, which is critical in ensuring safe workplace practices related to radiation exposure.
