Which of the following statements about airborne radon is true

Rationale

It is inexpensively detected and mitigated.

Airborne radon can be detected using relatively simple and low-cost testing kits, and effective mitigation strategies are also available that do not require significant investment. This accessibility makes it possible for homeowners to address radon issues in their living environments.

A (It has an easily detectable odor) YOUR ANSWER

Radon is a colorless, odorless gas, which means it cannot be detected by human senses. Unlike some other hazardous gases, radon does not have a distinctive smell, making it essential to use specialized testing methods for detection.

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

Radon can be present in any type of building, regardless of age or construction material. While certain geological conditions may increase radon levels in older homes, newer homes can also have significant radon concentrations if built in areas with high radon potential.

C (It is inexpensively detected and mitigated) CORRECT

As stated, radon can be detected using affordable testing kits, and many mitigation systems can be installed for a reasonable cost. This affordability encourages homeowners to test and address radon exposure effectively, providing peace of mind regarding indoor air quality.

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

Contrary to this statement, radon is a known carcinogen and can pose health risks to all individuals, regardless of smoking status. While smokers face higher risks of lung cancer from radon exposure, non-smokers are also at risk, and radon remains a significant health hazard in homes.

Conclusion

Radon poses a serious health risk, and while it is detectable and can be mitigated affordably, it is frequently misunderstood. The only true statement among the choices is that radon can be inexpensively detected and mitigated, allowing homeowners to take proactive measures against this harmful gas. Understanding the nature of radon is crucial for ensuring safe living environments.
