What potential long-term effect is associated with low-level radiation exposure?

Low-level radiation exposure is associated with an increased risk of fatal cancer over the long term. This association stems from the fact that radiation can damage the DNA within cells, and while some damage can be repaired by the body, persistent low-level exposure may lead to genetic mutations. If these mutations occur in genes responsible for controlling cell growth and division, it can result in the development of cancerous cells.

Epidemiological studies have shown that individuals exposed to even low levels of radiation over extended periods have a higher likelihood of developing certain types of cancer, particularly leukemia and solid tumors, compared to those who are not exposed. The effects may take years or even decades to manifest, which highlights the importance of monitoring radiation exposure over the long term and implementing safety measures to minimize unnecessary exposure.

This understanding of the relationship between low-level radiation and cancer risk is fundamental for nuclear facility workers and employees in various professions involving radiation exposure, establishing guidelines for maximum allowable doses to protect their health.
