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 there are also effective methods for mitigating its presence in homes, making it manageable and safe when appropriate actions are taken.

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

Radon is a colorless, odorless gas, which means it cannot be detected by smell. This property makes it particularly dangerous, as people may unknowingly be exposed to high levels without any sensory warning.

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

Radon can be found in any type of building, regardless of its age or construction materials. It typically emanates from the ground and can seep into homes through cracks in foundations, making it a concern for both new and old structures alike.

C (It is inexpensively detected and mitigated.) CORRECT

Radon detection is feasible with various affordable testing kits available for homeowners, and remediation methods, such as venting systems, can be installed at a reasonable cost. This accessibility enables homeowners to address radon issues effectively.

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

While smoking significantly increases the risk of lung cancer when combined with radon exposure, radon itself is still a known carcinogen. Non-smokers can also be affected by radon and should not assume they are safe from its harmful effects.

Conclusion

Understanding airborne radon is critical for health and safety. Among the choices provided, the ability to inexpensively detect and mitigate radon is vital, as it empowers individuals to take proactive measures against potential harm. The other statements either misrepresent radon's characteristics or downplay its risks, underscoring the importance of proper awareness and action regarding this hazardous gas.
