We perform radon testing using either charcoal canisters or a Radon Continuous Monitor. The charcoal canisters are less expensive than the continuous monitor, but only give a single reading integrated over a 48 hour time span. A major disadvantage of the charcoal canister is it is subject to tampering and precautions and steps need to be taken to avoid any tampering during the testing period.
A reliable and accurate way of testing in the limited time span of a real estate transaction is by using a "Radon Continuous Monitor. " The Continuous radon monitor takes 48 or more hourly readings during the test period and can detect any movement of the device, making it a more tamper resistant device. Also it is programmable and the test results can be printed out immediately after the completion of the test. Charcoal canisters can take a few days to analyse the test.
Our Professional Inspectors are Pennsylvania Radon Certified as Radon Testing Individuals.
General Radon Information
☀Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive,
colorless, odorless, tasteless noble gas, occurring naturally as an indirect decay product of uranium or thorium. Its most stable
isotope, Rn, has a half-life of 3.8 days. Radon is one of the densest substances that remains a gas under normal conditions. It is also
the only gas under normal conditions that only has radioactive isotopes, and is considered a health hazard due to its radioactivity.
Intense radioactivity has also hindered chemical studies of radon and only a few compounds are known.
☀As radon itself decays, it produces new radioactive elements called radon daughters or decay products. Unlike the gaseous radon itself, radon daughters are solids and stick to surfaces, such as dust particles in the air. If such contaminated dust is inhaled, these particles can stick to the airways of the lungs and increase the risk of developing lung cancer.
☀Radon is gaseous and easily inhaled. Thus, even in this age of nuclear reactors, naturally-occurring radon is responsible for the majority of the public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location.
☀Despite its short lifetime, some radon gas from natural sources can accumulate to far higher than normal concentrations in buildings, especially in low areas such as basements and crawl spaces due to its heavy nature. It can also be found in some spring waters and hot springs. Epidemiological studies have shown a clear link between breathing high concentrations of radon and incidence of lung cancer. Thus, radon is considered a significant contaminant that affects indoor air quality worldwide.
☀According to the United States Environmental Protection Agency, radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the United States. About 2,900 of these deaths occur among people who have never smoked. While radon is the second most frequent cause of lung cancer, it is the number one cause among non-smokers, according to EPA estimates.
