How is the cumulative effective dose limit (EDL) for a radiation worker calculated?

The cumulative effective dose limit (EDL) for a radiation worker is calculated using the formula of 10 mSv multiplied by the worker's age in years. This method is in accordance with guidelines set by regulatory bodies, which recognize that radiation exposure risk increases cumulatively over a person's working lifetime.

By using 10 mSv as a factor, the limit reflects a balancing act between allowing individuals to gain professional experience and ensuring their safety from long-term exposure to ionizing radiation. As a radiation worker ages, their cumulative exposure limit increases, reflecting their greater time spent in the field and the concomitant potential for radiation exposure associated with their occupational duties.

This specific calculation aims to protect the health of workers while allowing a reasonable amount of radiation exposure throughout their careers, mitigating risks as they accumulate over time. The other options do not align with these established safety measures and therefore do not reflect the standard practice for calculating the cumulative EDL.
