What is the maximum duration a short-term radon test can be deployed?

The maximum duration for a short-term radon test is indeed a significant aspect of radon measurement protocols. Short-term tests are designed to provide a rapid assessment of the radon levels in a given environment and typically range from a minimum of 2 days to a maximum of 90 days. This flexibility allows for variations due to seasonal changes, building occupancy, and other factors that can influence radon levels.

While some short-term tests may be conducted for just a day or two, the staggered testing window up to 90 days provides a comprehensive view of radon concentration changes over time. This extended duration is essential for capturing fluctuations and ensuring that the results reflect potential peak levels, especially in buildings where occupancy patterns may impact radon accumulation.

Therefore, the correct answer encompasses a broader timeframe indicative of the actual practice in radon measurement, while the other options either do not meet the minimum testing duration or do not cover the full potential range designated for short-term testing.
