The first step in radon mitigation is testing to see if the indoor air and/or domestic water radon concentrations should be reduced. No level of radiation is considered completely safe, but since radon cannot be totally eliminated governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced while recognizing that radon cannot be eliminated.

The World Health Organization's International Radon Project has recommended an action level of 2.7 pCi/l for radon in the air. Radon in the air is considered to be a larger health threat than radon in domestic water so the US Environmental Protection Agency recommendation is to not test for radon in water unless a radon in air test is above the action level. However, some US states, such as Maine where radon levels are higher than the national average, recommend that all well water should be tested for radon. The US government has not set an action level for radon in water.

Air-radon levels fluctuate naturally on a daily and seasonal basis. A short term test (90 days or less) might not be an accurate assessment of a home's average radon level, but are recommended for initial testing to quickly determine unhealthy conditions. Transient weather such as wind and changes in barometric pressure can affect short-term concentrations[1] as well as ventilation such as open windows and the operation of exhaust fans.

Testing for radon in the air is accomplished using passive or active devices placed in the building. Some devices are promptly sent to a laboratory for analysis, others calculate the results on-site. Radon-in-water testing requires a water sample being sent to a laboratory.

Retesting is recommended in several situations such as to double check test results before spending money on the installation of a mitigation system. Test results which exceed accuracy tolerances also require re-testing. When a mitigation system installation is warranted, a retest after the system is functional is advised to be sure the system is effectively reducing the radon concentration below the action level, and after any mitigation system repairs such as replacing a fan unit. Retesting is also recommended every ten years.

Frequently Asked Questions

Radon is a colorless, odorless radioactive gas that seeps up from the earth. When inhaled, it gives off radioactive particles that can cause lung cancer. According to EPA studies radon is the leading cause of lung cancer among non smokers.

The soil. Radon is produced from the natural decay of uranium that is found in nearly all soils. Uranium breaks down to radium. As radium disintegrates it turns into radon. As a gas, radon moves up through the soil and into the air you breathe.

While radon is present everywhere, and there is no known safe level, your greatest exposure is where it can concentrate indoors. And where you spend most time at home. Your home can have radon whether it be old or new and with or without a basement.

The goal of a radon mitigation system is to reduce the indoor radon levels to below the EPA action level of 4 pCi/L. A quality radon reduction (mitigation) system is often able to reduce the annual average radon level to below 2 pCi/L.
