What does Cumulative Effect mean in terms of radiation exposure?

Cumulative Effect in terms of radiation exposure refers to the idea that repeated or continuous exposure to radiation can lead to compounded detrimental effects on biological tissues. Therefore, the concept indicates that each exposure adds to the overall exposure, leading to potentially increasing harm.

The correct choice emphasizes that with repeated close exposures, the healing process does not keep pace with the damage being inflicted, resulting in a cumulative impact on health. This means tissues may not fully recover from one exposure before the next occurs, which can lead to long-term negative health outcomes.

The other options do not accurately reflect the principle of cumulative effect. For instance, stating that healing occurs faster with exposure fails to recognize the detrimental nature of radiation exposure. Suggesting that only a single exposure has consequences disregards the reality that even low levels of exposure can have significant ramifications over time. Lastly, claiming that exposure leads to immediate recovery fundamentally misrepresents the relationship between radiation and biological response, as exposure tends to lead to damage rather than recovery.
