Therefore, home owners ought to adhere to EPA's other recommendation to "think about" reducing radon if the examination result is over 2 pCi/L. An additional confounding issue is the accuracy of temporary radon test kits. EPA's guidelines on precision set individual family member mistakes at listed below 25% and radon company near me precision at coefficient of variant below 10% at 4 pCi/ L. But studies have shown that most radon packages do not meet these guidelines.

For information on short-term test devices and temporary testing method, see Annex 2 as well as Annex 3 respectively. Any type of temporary test ought to be adhered to up with a lasting measurement.

• Since Airthings radon detectors frequently monitor, they're considered "energetic".
• Attempting to open windows to potentially decrease the degrees of radon gas can negatively increase the radon levels up as well as cause for a greater radon level to be recorded.
• Yes, radon levels can change as a result of seasonal temperatures, low pressure tornados, changes in the geology listed below buildings as well as open residence problems.
• Radon is created from the breakdown of a chemical component named Uranium.

How bad is a radon level of 8?

Radon tests can have two types of error: “False positive” – the test result is above 4 pCi/L although the long-term average is below it. The homeowner may “waste money” on a radon mitigation system. “False negative” – the test result is below the Action Level but the long-term radon level is above it.

Does rain affect a radon test?
