What is Radon?

Radon is a radioactive gas that comes from the natural radioactive decay of radium, which is a natural decay product of uranium. Scientifically, “radon” is known to be radon-222, the most abundant isotope of the element radon. As a noble gas, radon is colorless, odorless and chemically inert and cannot be detected by human senses. Also, since radon is not chemically reactive with most materials, it will move freely as a gas. Radon has a radiological half-life of 3.8 days, and can move substantial distances from its point of origin.

As radon-222 decays, the first four radioactive isotopes formed are polonium-218, lead-214, bismuth-214 and polonium-214. They are commonly referred to as “radon daughters” or “radon progeny. These short-lived isotopes are not gases but are chemically active solids. They are present in any environment where radon is found and, like radon, cannot be detected by human senses.

Uranium is a natural part of the earth’s crust; therefore, radium and radon are also naturally present. Since uranium and radium concentrations vary throughout the earth’s crust, radon concentrations will also vary. The amount of radon gas that escapes into the atmosphere is dependent on the depth at which it is formed and the permeability of the surrounding earth. Radon formed in the top 10 meters of soil and rocks provide the largest component of radon entering the atmosphere.

The second most important contributor to radon is emanation from groundwater. Underground radon is readily carried in groundwater and when this groundwater surfaces, most of the radon is released to the atmosphere.

Other sources of radon are very small contributors and are largely due to human activities. For example, there are radium-rich industrial by-products spread upon the earth, and sometimes construction materials are produced from raw materials that contain uranium or radium.

Find The Radon Potential In Your Area

The Map was developed using five factors to determine radon potential: indoor radon measurements; geology; aerial radioactivity; soil permeability; and, foundation type.

Radon potential assessment is based on geologic provinces. Radon Index Matrix is the quantitative assessment of radon potential. Confidence Index Matrix shows the quantity and quality of the data used to assess radon potential. Geologic Provinces were adapted to county boundaries for the Map of Radon Zones.

Why Test for Radon?

According to the Surgeon General of the United States, radon is the second leading cause of lung cancer within the USA.

Radon is estimated to cause about 21,000 lung cancer deaths per year, according to EPA’s 2003 Assessment of Risks from Radon in Homes (EPA 402-R-03-003). The numbers of deaths from other causes are taken from the Centers for Disease Control and Prevention’s 1999-2001 National Center for Injury Prevention and Control Report and 2002 National Safety Council Reports.

Only smoking causes more lung cancer deaths, but if your home has high radon levels and you smoke, then your risk of lung cancer is especially high. The Environmental Protection Agency (EPA) and the American Lung Association agree that long term exposure to elevated levels of radon pose a significant health risk to you and your family. Therefore, since radon is a colorless, odorless, and tasteless gas, the only way to determine if radon is in your home is by testing.
