What is the purpose of secondary chambers in radon testing?

The purpose of secondary chambers in radon testing is to improve test accuracy. Secondary chambers are used to create a controlled environment for monitoring radon levels and reducing fluctuations that might be caused by external factors. By utilizing secondary chambers, it allows testers to isolate the radon measurements from influences such as air pressure changes, temperature variations, or humidity levels, which can all affect the accuracy of radon detection. Therefore, employing these chambers enhances the precision of the testing process and ensures that the results reflect true radon levels in a specific area.

This focus on accuracy is essential for making informed decisions about radon mitigation and ensuring that the readings can be trusted when assessing risk levels in various environments.
