Question 30

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

It is advisable for prospective buyers to check for radon in the property they wish to purchase, as radon is recognized as a significant health risk and a leading cause of lung cancer.

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

This option is incorrect because it dismisses the importance of testing for radon. Regardless of location, radon can be present in various concentrations, and its presence cannot be assumed to be unlikely without proper testing.

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

This statement is misleading and incorrect. Radon exposure poses a risk to all individuals, not just smokers. Non-smokers are still at risk of developing lung cancer due to radon exposure, making this option inadequate.

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

This option is correct as it accurately reflects the necessity of radon testing. The acknowledgment of radon as a carcinogen highlights the potential health risks associated with it, thereby justifying the need for testing prior to purchasing property.

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

This choice is incorrect because radon is colorless, odorless, and tasteless, meaning it cannot be detected without specialized testing equipment. Relying on sensory detection is highly misleading and could result in serious health risks.

Conclusion

The correct answer, C, emphasizes the importance of radon testing due to its classification as a health hazard linked to lung cancer. All other options fail by either minimizing the risk, providing incorrect information about detection, or suggesting that certain demographics are exempt from risk, which is not the case. Thus, it is crucial for buyers to conduct radon testing to ensure their safety.
