At a radon level of 4 pCi/L, what is the risk of lung cancer for smokers?

At a radon level of 4 pCi/L, the calculated risk of lung cancer for smokers is indeed 62 per 1,000 smokers. This statistic is derived from the epidemiological studies that have established a correlation between radon exposure and lung cancer, particularly emphasizing its effects on individuals who smoke.

The risk is notably higher for smokers compared to non-smokers due to the cumulative effects of tobacco smoke and radon exposure on lung tissue. It is well-established that smoking and radon are both significant risk factors for developing lung cancer, and their combined effects significantly elevate the probability of illness.

Understanding this relationship is crucial for radon mitigation specialists, as it highlights the importance of monitoring and reducing radon levels in homes, especially for occupants who smoke. This combined risk assessment demonstrates why initiatives aimed at reducing radon exposure can have a transformative impact on lung cancer incidence, particularly in populations already at risk due to smoking.
