What type of risk does radon exposure represent?

Radon exposure represents cumulative risk because it reflects the prolonged and ongoing nature of exposure to radon gas over time, which can lead to an increased likelihood of developing health issues, particularly lung cancer. Unlike instantaneous risks, which refer to immediate and acute dangers, cumulative risk is associated with the accumulation of exposure that occurs with time. This is particularly relevant for radon, as the risk increases with each year of exposure, emphasizing the importance of long-term monitoring and mitigation strategies in residential and other environments where radon may be present.

By recognizing radon exposure as a cumulative risk, it highlights the necessity for continuous assessment and action to reduce levels of radon to safe limits, rather than solely focusing on immediate threats or external factors that might not provide the same depth of understanding of long-term health implications.
