What is a potential long-term effect of radiation exposure?

The potential long-term effect of radiation exposure that is widely recognized is an increased risk of cancer. Radiation has the ability to damage cellular DNA, leading to mutations that can result in the development of cancer over time. This relationship between radiation exposure and cancer risk is well-documented in various studies and is a critical consideration in radiation safety protocols.

Unlike the other options that suggest beneficial effects, the reality is that radiation exposure does not lead to improved healing rates, strengthened immune systems, or enhanced cognitive functions. Instead, chronic or high levels of radiation exposure have been linked directly to harmful health effects, including various forms of cancer. This understanding is essential for effective radiation safety training and ensuring the protection of individuals working with or around radiation.
