What is the typical duration for an Open-Face Activated Charcoal Test?

The typical duration for an Open-Face Activated Charcoal Test is 2-3 days. This timeframe is established to ensure that the test can accurately capture the radon levels present in the home or environment being assessed. During these 2-3 days, the activated charcoal is exposed to the air in the area being tested, allowing it to adsorb radon gas effectively.

This duration strikes a balance, providing sufficient time for the charcoal to gather a meaningful sample without being too short to miss fluctuations that could occur. A period less than 2 days might not allow for a comprehensive assessment, whereas longer durations could introduce variables such as changes in air circulation or environmental conditions that might skew the results. By adhering to the 2-3 day timeframe, the test results can be both reliable and representative of typical radon levels experienced over a short-term exposure, which is essential for effective radon mitigation planning.
