Question 18

It is inexpensively detected and mitigated.

Airborne radon is a radioactive gas that can be detected through relatively simple and cost-effective testing methods. Mitigation strategies are also available at a reasonable cost, making it feasible for homeowners to address radon levels in their homes.

A) It has an easily detectable odor.

This statement is incorrect because radon is a colorless, odorless gas. Therefore, it cannot be detected by smell, which is why testing is essential for identifying its presence in indoor environments.

B) It is only found in older wood frame structures.

This option is also incorrect. Radon can be found in homes of any age and construction type, not just older wood frame structures. Its presence is primarily related to the geological conditions of the area rather than the age or type of the building.

C) It is inexpensively detected and mitigated.

This statement is true as radon testing kits are widely available at low costs, and there are effective mitigation systems that can be installed without significant expense. This accessibility makes it practical for homeowners to ensure safe indoor air quality.

D) It is not harmful to adults who do not smoke.

This statement is misleading. While non-smokers have a lower risk of developing lung cancer from radon exposure compared to smokers, radon is still a known carcinogen and can pose health risks to all individuals, regardless of smoking status.

Conclusion

Option C is the only statement that accurately reflects the realities of airborne radon detection and mitigation. All other options either present false information about radon's characteristics or its health risks, failing to address the key points necessary for understanding the importance of radon management.
