How does the risk of asbestos exposure change over time?

The risk of asbestos exposure increases with the duration and intensity of exposure due to the cumulative nature of its effects on human health. As individuals are exposed to asbestos fibers over extended periods or at higher intensities, the likelihood of developing serious health issues, such as lung cancer or mesothelioma, rises significantly. This is because the risk of asbestos-related diseases is not only about the initial exposure but also heavily influenced by the amount and length of time an individual has been exposed to the hazardous material.

In contrast, other provided options do not accurately reflect the dynamics of asbestos risk. The notion that the risk decreases after initial exposure fails to consider the long-term health implications associated with cumulative exposure. Similarly, the idea that the risk remains constant disregards the evidence that duration and intensity significantly alter health outcomes. Lastly, suggesting that the risk is only high in the first year of exposure ignores the reality that asbestos-related conditions often develop many years after exposure, highlighting the importance of ongoing risk as exposure continues.
