Which health statistic correlates with radon exposure for non-smokers?

• A. 10/1000
• B. 7/1000
• C. 15/1000
• D. 5/1000

Answer: (B)

For non-smokers, the health statistic that correlates with radon exposure is 7 lung cancer deaths per 1,000 people. This figure is based on epidemiological studies that show the increased risk of lung cancer associated with prolonged radon exposure, primarily for individuals who do not have the added risk factor of smoking.

Radon is known to be a significant indoor air pollutant and a leading cause of lung cancer in non-smokers, coming second only to tobacco use in terms of risk factors for lung cancer overall. The estimate of 7/1000 reflects the statistical analysis of large populations exposed to various levels of radon, taking into account factors such as exposure duration and concentration levels that are typical in homes.

By understanding this statistic, individuals and professionals in the field can better communicate risks and motivate public health measures to mitigate radon exposure in homes, especially in areas known to have higher concentrations of radon gas.
