Where should I place a radon kit?
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.
What should you not do 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.
How many radon detectors are needed in a home?
Because areas under your home are normally the first place radon gas will accumulate, you should consider placing one radon detector for every 2000 uninterrupted sq ft, and in frequently occupied rooms.
Are radon detectors accurate?
The National Radon Safety Board evaluates radon measurement devices in cooperation with the US Environmental Protection Agency. It requires that the individual relative error of each device be less than or equal to 20.0% and that the precision error of all devices be less than or equal to 20.0%.
Is radon in the air outside?
Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation.
How do open windows affect radon testing?
Don’t just open the windows However, opening the windows in your house will have little effect on your home’s radon levels. What’s more is that, even if radon levels are reduced with the opening of your windows, the levels will return to their higher rates once the windows are closed.
Do ceiling fans help with radon?
Ceiling fans can reduce radon levels by 50%. If used along with positive ion generators, ceiling fans are capable of reducing radon levels by 90%. This is achieved by a phenomenon called plate-out, which neutralizes radio-active particles.
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.
Is it OK to live in a house with radon?
If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Over time, these radioactive particles increase the risk of lung cancer. It may take years before health problems appear. People who smoke and are exposed to radon are at a greater risk of developing lung cancer.
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.
Should you walk away from a house with radon?
Should you walk away from the deal? Consumer Reports says you don’t have to. Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home.
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.
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).
What can make a radon test high?
High winds can either be pushing out the radon (creating high pressure in the home) or “vacuuming” it in (creating low pressure in the home). In most cases, high winds increase radon levels in homes. Cold winter weather – snow, ice, colder temperatures, etc.
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 do you place a radon detector?
Detectors should be placed approximately 40 cm (16 inches) from an interior wall or approximately 50 cm (20 inches) from an exterior wall. The primary purpose of testing is to assess the level of radon to which occupants are exposed.
How quickly can radon affect you?
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.
