The cumulative exposure limit indeed increases in proportion to age. This is based on the principle that as a person ages, they have more years of potential exposure to radiation. Regulatory bodies often set occupational exposure limits to account for this, allowing a higher total exposure limit for workers as they get older. The reasoning behind this is related to the biological understanding that younger individuals may be more susceptible to the effects of radiation, while older individuals may have a decreased lifetime risk due to their shorter remaining lifespan.

As a result, cumulative exposure limits are typically calculated as a function of age, allowing for increased limits that reflect the lifetime exposure an individual can accumulate. This concept is critical in radiation protection practices, as it ensures that exposure remains within acceptable safety thresholds while considering the individual's age-related risk.

The other options do not accurately reflect how cumulative exposure limits are structured in relation to age, as they either suggest a static limit or imply limits that are not applied beyond a certain age, which does not align with established safety standards.
