Radon tests work by counting or tracking the amount of radon in the air. Charcoal devices absorb radon so that the radioactive particles can be counted at a lab for accurate radon level estimates. Alpha-track test kits have a plastic film that becomes marked by alpha particles that strike it.
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.
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 does radon testing work?
Radon tests detect either radon gas directly or the daughter products of radon’s radioactive decay. In the laboratory, the radioactive particles emitted from the charcoal are counted directly by a sodium iodide counter or converted to light in a liquid scintillation medium and counted in a scintillation detector.
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.
Can I test for radon myself?
You can do it yourself or hire someone to do it for you. from a hardware store. Or you can order one by calling 1-800-SOS-RADON (1-800-767-7236) or going to the National Radon Program Services website (http://sosradon.org/test-kits). Set up the testing device to check the air for radon.
Can radon tests be wrong?
The short answer is yes, as errors can happen with any type of test, but the likelihood of a wrong radon level reading changes greatly based on a variety of factors.
Will running a fan reduce radon?
Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Running a window fan in a basement window reduces radon levels, but only if the fan blows air into the basement.
Can you open basement door during radon test?
It is much preferred not to open the basement door during the radon test. This is because radon is an odorless and colorless gas that mingles with room air. If a portal of entry is open, you risk getting skewed results of a much lower radon concentration level.
Do open windows affect radon testing?
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.
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.
How do you manipulate a radon test?
Some of these methods for how to pass a radon test include: Open windows. By opening the windows, you increase fresh air circulation and reduce the concentration of radon in the home. Install basement vents. Use fans. Create exits. Mitigation.
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.
Do Ceiling fans reduce 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 does charcoal radon test work?
Charcoal tests absorb the radon in the air for a specified amount of time, and once in the lab, the radioactive particles emitted by the charcoal are counted or converted to light, giving a radon level readout. Alpha track tests use a plastic film that is etched by the alpha particles that strike it.
How do I get rid of radon in my basement?
Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.
How common is radon in homes?
It’s common: About 1 in every 15 homes has what’s considered an elevated radon level. The gas is odorless and invisible, says the EPA, and it causes no immediate symptoms, so the only way to know if your home is affected is by testing your individual residence.
