Are home radon test kits accurate?

Where is radon most commonly found?

Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour.

How do you eliminate radon?

Other radon reduction techniques that can be used in any type of home include: sealing, house or room pressurization, heat recovery ventilation and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction.

Do air purifiers help with radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.

How do I know if I have radon in my basement?

How do you read radon results?

Interpreting Your Radon Test Results Greater than or Equal to 4.0 pCi/L. Above 4.0 pCi/L, you are putting yourself at unusually high risk for lung damage and cancer. Between 2.7 and 4.0 pCi/L. Less than 2.7 pCi/L.

How long do you have to be exposed to radon for it to be harmful?

Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop.

Will opening the basement windows before a radon test lower the results?

Where is the best place to put a radon test?

Place a radon detector in the breathing zone, 2-6 feet above the floor, and away from drafts, exterior walls, sumps, drains, windows or doors. Radon may enter a building through cracks in the foundation or through sumps or drains and will usually be higher near these entry points.

Are charcoal radon tests accurate?

Charcoal Radon Test Kits These tests are the cheapest and quickest options for measuring radon levels in your home, but they are also the least accurate because they are susceptible to spikes in radon levels and interference during shipping for lab tests.

What type of soil is radon found in?

The U.S. Geological Survey explains that radon moves easily and quickly through porous soils, like sand and gravel, and slower through more solid soils, clay being one such example. Moisture has a lot to do with this.

What are 5 facts about radon?
