Question 67

They should do so, because radon is now considered to be one of the causes of lung cancer.

Radon is a known carcinogen and is associated with an increased risk of lung cancer, making it essential for prospective buyers to test for its presence in a property before making a purchase.

A) it is unlikely that radon would be a problem in that area.

This option is incorrect because it downplays the potential risk of radon. Radon levels can vary significantly by location, and assuming it is unlikely without testing could lead to serious health risks for the buyers.

B) as long as they are non-smokers, it should not be an issue.

This response is misleading as it suggests that non-smokers are not at risk from radon exposure. Radon is harmful regardless of smoking status, and even non-smokers can develop lung cancer from high radon levels.

C) they should do so, because radon is now considered to be one of the causes of lung cancer.

This is the correct response because it accurately reflects the current understanding of radon as a significant health hazard. Testing for radon is a prudent step for buyers to protect their health and make informed decisions regarding their property investment.

D) they need not do so, because if radon were present, there would be an odor that would make it easy to detect.

This option is incorrect as radon is a colorless, odorless gas, making it impossible to detect by smell. Relying on odor as a means of detection can lead to dangerous assumptions about the safety of the property.

Conclusion

The correct answer emphasizes the importance of testing for radon due to its link to lung cancer, which is a critical health consideration for prospective buyers. Other options either underestimate the risk or provide misleading information about detecting radon, reinforcing the necessity of proactive testing in real estate transactions.
