What is the maximum duration for a short radon test?

A short-term radon test is typically designed to assess radon levels in a home or building over a brief period to provide timely results. The maximum duration for these tests is 90 days, and they are commonly conducted over periods ranging from a few days to three months. Conducting a shorter test helps homeowners quickly understand whether radon mitigation methods are needed, particularly in situations where immediate action may be required for health and safety reasons.

Tests lasting more than 90 days are generally classified as long-term tests. These longer tests provide an average radon concentration over time, accounting for seasonal variations and other factors that can affect radon levels. The choice of test duration directly influences the reliability of the readings, with short tests offering quicker but potentially less comprehensive data.
