Question 71

It is inexpensively detected and mitigated.

Airborne radon can be detected through affordable testing methods and there are also cost-effective solutions available for its mitigation, making it manageable for homeowners and building managers.

A) It has an easily detectable odor.

This statement is incorrect because airborne radon is a colorless, odorless gas, which means it cannot be detected by smell. Detection requires specific testing methods rather than sensory perception.

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

This option is misleading as radon can be found in various types of buildings, including newer structures, and is not limited to older wood frame constructions. Radon can enter homes through cracks in floors, walls, and other openings.

C) It is inexpensively detected and mitigated.

This statement is correct. Airborne radon can be detected using relatively low-cost testing kits, and remediation strategies are available that are also economically feasible, making it accessible for most homeowners.

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

This is inaccurate since radon exposure is known to pose health risks, including lung cancer, even for non-smokers. The dangers of radon are independent of smoking status, and non-smokers can still be adversely affected by high radon levels.

Conclusion

The correct answer is C, as it highlights the affordability of detecting and mitigating airborne radon, which is crucial for public health awareness. Options A, B, and D are incorrect as they misrepresent the nature of radon and its risks, thus failing to provide accurate information regarding this environmental concern.
