What is a disadvantage of long-term radon testing?

The selection of the option indicating that long-term radon testing "requires more time" accurately highlights a key consideration in the evaluation of radon levels within a home or building. Long-term radon tests typically last for a duration exceeding 90 days, which allows for a comprehensive assessment of radon concentration over an extended period. This is important because radon levels can fluctuate based on various environmental factors, and a longer testing duration provides a more representative average of the radon exposure over time.

While long-term testing is essential for gaining an understanding of the annual average radon exposure, the downside is that it requires patience and commitment from homeowners or testers. Waiting several months for results can be a disadvantage for those seeking immediate feedback on radon levels, particularly if remediation actions are needed quickly.

In summary, the time commitment associated with long-term radon testing is a crucial aspect to consider, as it extends the duration required for obtaining results compared to short-term tests, which deliver quicker assessments.
