Are home radon test kits accurate?
“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.
Where should you place a radon detector?
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.
How do you prepare for a radon test?
Begin by keeping the home’s doors and windows closed for up to 12 hours prior to the radon test.How to prepare for a radon test Have windows open. Have ceiling fans operating. Have attic fans operating. Have humidifiers or dehumidifiers operating. Have fireplaces operating (chimney dampers should be closed).
Will opening the basement windows before a radon test lower the results?
Unfortunately, no, opening the windows does not reduce radon. It is not a gas that will just permanently escape the home like smoke from something burning in the oven. The radon may seem to leave when the windows are open, but as soon as they are closed, it is back.
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.
Which room is best for radon test?
This means testing in the lowest level (such as a basement), which a buyer could use for living space without renovations. The test should be conducted in a room to be used regularly (such as a family room, living room, playroom, den, or bedroom); do not test in a kitchen, bathroom, laundry room or hallway.
Can you drink water with radon?
Health Effects Radon can be inhaled from the air or ingested from water. Inhalation of radon increases the chances of lung cancer and this risk is much larger than the risk of stomach cancer from swallowing water with a high radon concentration. Generally, ingested waterborne radon is not a major cause for concern.
How do you test for radon in a basement?
You can hire a professional tester or do it yourself with a kit you buy at a hardware store or online. Follow the instructions for leaving the kit in your house for the required number of days. Then mail it to a lab and wait for the results. If radon levels in your home are high, you can take steps to lower them.
What time of year is radon highest?
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
How does opening windows affect a radon test?
Opening windows at the upper levels actually has the potential to increase radon levels during a short-term test. This is because the increased amount of dilution air that is brought into the house will typically be enough to offset any additional radon gas brought into the house.
Can you run a ceiling fan during a radon test?
Turn off all air moving devices during the test. This would include ceiling fans, dehumidifiers, regular fans, HEPA or any other kind of filtering device that moves air. Do not operate fireplaces or heating stoves during the test unless they are your main source of heat.
Will running a fan reduce radon?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, 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 home.
How do you skew a radon test?
Rain during the test period can skew test results—sometimes quite dramatically. This is because rain drives radon out of the ground, which results in a high radon level reading.
Should I air out my basement before a radon test?
Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open. A fan blowing air out of the basement increases negative pressure, which can actually increase radon levels.
What are the symptoms of radon in your home?
A persistent cough could be a sign that you have radon poisoning. Persistent cough. Hoarseness. Wheezing. Shortness of breath. Coughing up blood. Chest pain. Frequent infections like bronchitis and pneumonia. Loss of appetite.
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?
Here are a few facts about radon, and what you can do to help keep your family healthy and safe. Radon is radioactive. Radon is a naturally occurring radioactive gas. Radon causes cancer. No immediate symptoms. You must test for radon. Radon is present indoors and outdoors. Radon can build up in any building.
What can cause a false positive radon test?
Can Radon Tests Be Wrong? Barometric pressure. Temperature/Season. House construction. Rain soaked ground. HVAC system. Improper placement of the device.
Is radon testing necessary?
When you breathe air containing radon, you increase your risk of getting lung cancer. If you smoke and your home has high radon levels, your risk of lung cancer is especially high. You Should Test for Radon. Testing is the only way to find out your home’s radon levels.
Would a gas leak affect a radon test?
Most likely not; even so, by now, the gas should have cleared. That saidthe nature of radon is that the levels fluctuate.
