What would be the cumulative dose limit for a 30-year-old worker?

The cumulative dose limit is designed to ensure the safety of workers in environments where they may be exposed to ionizing radiation. This limit is typically calculated based on age, applying a formula that involves multiplying the worker's age in years by a specific factor, often 1 rem.

For a 30-year-old worker, the calculation would be as follows: 30 years multiplied by 1 rem equals a cumulative dose limit of 30 rem. This limit is intended to protect the health and safety of radiological workers, ensuring that their exposure remains within acceptable thresholds over their lifetime.

The other options represent doses that do not align with the established guidelines for cumulative dose limits based on age.
