Prospective buyers ask their agent whether they should test for radon. The agent should tell them

Rationale

They should test because radon causes lung cancer.

Radon is a colorless, odorless gas that can accumulate in homes and is known to be a leading cause of lung cancer among non-smokers. It is essential for prospective buyers to conduct radon testing to assess the safety of their potential residence and take necessary mitigation measures if high levels are detected.

A (it is unlikely radon would be a problem) YOUR ANSWER

This statement downplays the risks associated with radon exposure. While it may be true that certain geographic areas have lower radon levels, it is impossible to guarantee that radon will not be a problem without testing. Therefore, this response could lead to complacency and increased health risks.

B (non-smokers need not worry) YOUR ANSWER

This choice is misleading as radon is particularly dangerous for non-smokers. In fact, non-smokers are at risk of developing lung cancer from radon exposure, which makes testing critical for everyone, regardless of their smoking status. This option incorrectly minimizes the risk for a significant portion of the population.

C (they should test because radon causes lung cancer) CORRECT

Radon is a known carcinogen, and prolonged exposure can lead to serious health issues, including lung cancer. This statement emphasizes the importance of testing, as it addresses the real and significant risks posed by radon in homes, making it the most responsible advice for prospective buyers.

D (they need not test because radon has an odor) YOUR ANSWER

This statement is incorrect since radon is both colorless and odorless. The lack of any sensory detection means that relying on smell as a safety measure is ineffective. This response could potentially lead buyers to forgo testing, exposing them to unnecessary health risks.

Conclusion

Testing for radon is a crucial step for prospective homebuyers due to its severe health risks, particularly lung cancer. While some choices may downplay the significance of radon or misrepresent its nature, the emphasis on testing as a preventive measure underscores the importance of ensuring safe living conditions. Awareness and action against radon exposure are vital for safeguarding health and well-being.
