Which of the following is a potential consequence of excessive occupational radiation exposure?

Excessive occupational radiation exposure is particularly concerning because it increases the risk of developing cancer. Ionizing radiation has the potential to damage DNA within cells, leading to mutations that can ultimately result in cancerous growths. This risk is well-documented and is a fundamental reason why strict safety protocols and exposure limits are enforced in environments where radiation is present.

While increased fatigue, shortened lifespan, and acute radiation syndrome can all arise from radiation exposure, they are not as directly linked to ongoing occupational exposure as cancer. Increased fatigue can occur due to a variety of reasons and is not specific to radiation. Shortened lifespan can be an indirect consequence of cumulative health effects over many years but does not necessarily provide a clear connection to radiation exposure. Acute radiation syndrome is primarily associated with high doses of radiation received in a short time frame, such as in accidents or catastrophic events, rather than ongoing occupational exposure.
