Which of the following statements about airborne radon is true?

Rationale

It is inexpensively detected and mitigated.

Airborne radon can be detected using relatively low-cost testing kits, and effective mitigation strategies are available, making it accessible for homeowners to address radon levels 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 smell. This characteristic makes it essential to use specific testing methods to identify its presence, as relying on sensory detection is ineffective.

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

Radon can be found in homes of any age and construction type, not just older wood frame structures. It originates from the natural decay of uranium in soil and rock and can seep into buildings regardless of their construction materials or age.

C (It is inexpensively detected and mitigated) CORRECT

Radon testing kits are available at a low cost, and there are multiple affordable mitigation techniques that can effectively reduce radon levels in homes. This accessibility makes it feasible for homeowners to ensure their living spaces are safe from radon exposure.

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

While non-smokers are at a lower risk compared to smokers, radon exposure can still pose health risks, including lung cancer, even in adults who do not smoke. The danger of radon is related to cumulative exposure over time, irrespective of smoking status.

Conclusion

Understanding airborne radon is crucial for public health. The true statement about radon emphasizes the affordability of its detection and mitigation, which empowers homeowners to take proactive measures. In contrast, the other options misrepresent radon's characteristics or risks, highlighting the importance of accurate information in managing environmental hazards effectively.
