Which of the following statements about airborne radon is true?

Rationale

It is inexpensively detected and mitigated.

Airborne radon is a naturally occurring radioactive gas that can accumulate in buildings, particularly in basements. Detection is straightforward and affordable, with various testing kits available for homeowners, and mitigation strategies can also be implemented at a relatively low cost to reduce radon levels effectively.

A (It has an easily detectable odor.) YOUR ANSWER

Radon is an odorless, colorless, and tasteless gas, making it impossible to detect without the use of specialized testing equipment. This lack of sensory detection is one of the reasons why radon poses a significant risk, as individuals may not realize they are exposed to harmful levels.

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

Radon can be found in any type of building, regardless of age or construction material. It originates from the natural decay of uranium in soil, rock, and water, and can enter homes through cracks in floors, walls, and other openings. Therefore, limiting its presence to older wood frame structures is inaccurate.

C (It is inexpensively detected and mitigated.) CORRECT

Detection and mitigation of radon are indeed cost-effective processes. Homeowners can purchase radon test kits for a low price, and professional mitigation services are available at a reasonable cost, making it accessible for most households to address radon issues properly.

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

While non-smokers face a lower risk compared to smokers, radon exposure is still dangerous for everyone. The World Health Organization indicates that radon is the second leading cause of lung cancer after smoking, emphasizing that it poses a health risk to all individuals regardless of their smoking status.

Conclusion

Radon is a serious health hazard that can be inexpensively detected and mitigated, ensuring safer living environments. Misconceptions about its odorlessness and the types of buildings it can inhabit contribute to the risks associated with exposure. Awareness and proactive measures are essential in preventing radon-related health issues, making affordable detection and mitigation crucial for all homeowners.
