Units of Measure. Radon Measurements. A becquerel is a measure of radioactivity. One becquerel (Bq) is equal to one radioactive decay per second. Radon concentrations in air are usually measured in becquerels per cubic meter (Bq/m 3). That’s the amount of radon (becquerels) in a volume of air (cubic metre).

What are the measurements for radon? Radon Measurement & Testing. Radon is measured in picocuries per liter, abbreviated pCi/L. The average levels found outdoor air in the United States is 0.4 pCi/L and average indoor air is 1.3 pCi/L. The guidance from the EPA recommends mitigation be considered in homes where testing finds levels at or above 4.0 pCi/L.
What is the EPA standard for radon? Radon Act 51 passed by Congress set the natural outdoor level of radon gas (0.4 pCi/L) as the target radon level for indoor radon levels. Unfortunately two-thirds of all homes exceed this level. The US EPA was tasked with setting practical guidelines and recommendations for the nation. To this end, the US EPA has set an action level of 4 pCi/L.
What is an acceptable level of radon? The EPA does not advise individuals to consider taking action until radon levels are 2 pCi/L or greater. Therefore, one may interpret that to mean that an acceptable radon level is anything under a 2 pCi/L, especially for longer term exposure. Anything more than a 4 pCi/L should definitely be fixed, according to the EPA.

Are radon measurements accurate and reliable? While any measurement system has an associated variability in precision and accuracy, we expect that radon test devices that are used properly will provide accurate and reliable results. The study presented here only represents a part of the picture of accuracy and reliability.
How to test your home for radon? Radon can enter your home through areas at ground level or above a crawl space, so you’ll want to test these areas in addition to your basement. Place the test kit on a shelf or table against an interior wall that is free from ventilation sources like vents or air returns.
How do you test for radon? “The only way to detect it is to do a test, and there’s a couple different ways today that that can be done,” said Mark Beauregard, who owns Radon Mitigation Services of Maine in Holden. “Number one, you can find radon tests at hardware stores and Home Depot and Lowe’s.”
What is the unit of measurement for radon? The preferred radon level measurement unit is Becquerels per cubic meter, Bq/m3. One Becquerel equals one radioactive disintegration per second. The best radon level measurement would be zero. Unfortunately, that’s not possible.

What is a dangerous level of radon? The U.S. Environmental Protection Agency (EPA) has determined that measurements of 4 pCi/L (picocuries per liter) or higher are considered dangerous levels. This radon level is largely unsafe and is 10 times higher² than the average outdoor air levels. At what level is radon dangerous? Levels of 4 pCi/L or higher are considered hazardous.
