How do you lower radon levels before a test?

In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) or actively (with the use of a fan). Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the house.

What happens when a house fails a radon test?

The words radon test “failed” or radon test “passed” are thrown around out there. Pass/fail should not be used to determine radon safety. No level of radon is safe. … Meaning, take action to reduce radon levels that are greater than four picocuries per liter.

Does opening doors affect a radon test?

There are many factors that affect Radon levels in a house. Opening windows and exterior doors may cause radon levels to drop as indoor air gets diluted by outside air.

Is radon higher in summer or winter?

To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.

Can you enter a house during a radon test?

No, you don’t have to leave your house. But you do need to keep the windows closed during the testing, and only open doors as much as necessary to go in and out.

Is a 48 hour radon test accurate?

Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time. Summary: A new study finds the only reliable way to measure exposure to radon gas is with a long-term testing kit, 90 or more days. … “Radon gas levels can fluctuate wildly day to day,” says Dr.

What happens if you open windows during a radon test?

Opening windows at the upper levels actually has the potential to increase radon levels during a short-term test. … In reality, if enough windows are opened, very small amounts of wind will be far larger factors than stack effect, and radon levels will probably decrease.

What happens if you are exposed to radon?

Being exposed to radon for a long period of time can lead to lung cancer. Radon gas in the air breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung cancer.

Does Radon only stay in the basement?

Because it is often found unexpectedly in basements, some people mistakenly believe that it only occurs in basements. … The fact that porous foundation walls allow radon gas to enter a home is no secret and with most basements containing a sump well, there are many access points from which radon can enter a home.
