What is Radon?
Radon is a colorless and odorless gas that is present indoors and outdoors. In 1990, the National Safety Council conducted a study on the effects of this naturally occurring gas. It is estimated that radon can cause 7,000 to 30,000 cancer related deaths each year. Due to its harmful effects, radon is the second leading cause of lung cancer, next to smoking.
The goals of the Navajo Nation Environmental Protection Agency's Radon Program is to ensure all homes and tribal offices be tested at least once and all schools and day cares to be tested yearly. From the Ground to our Homes, Schools, and Offices.
Radon comes from uranium. Uranium is found in soil and rock, such as phosphate, pitchblende, shale, and granite. As uranium decays, it produces radium. In return, decaying radium produces radon. Radon gas travels upward from the ground and enters buildings and homes through dirt floors and through cracks in the foundation and basement. Radon also travels through drains, walls, and other openings where it is trapped. Radon in the outside air is in very low concentrations and is not a problem. It can also come from your water, if you water is supplied by a well. If a well serves as your water source and your home has been tested to have a level of 4 pCi/l or higher, you might consider having your water tested.
Why is Radon Harmful?
Radon is a radioactive gas, making it harmful to our bodies. Long-term exposure to radon, in small or large amounts, can develop into lung cancer. Decaying radon releases tiny radioactive particles that can be inhaled. These particles attch to lung tissue and cause damage, resulting in lung cancer. The chances of developing lung cancer are increased for smokers.
How much Radon is Safe?
Radon is not safe, in any amount or at any level. The recommended action level for radon is 4 pCi/l. Level of radon vary greatly from place to place; the only way to know the radon levels in a building is to test.
How Can We Help?
The Radon Program, a division of the Navajo Nation Environmental Protection Agency, is dedicated to informing the public about Radon and its health effects. The program conducts routine tests in the area schools and tribal buildings. Tests are also administered in private homes at the request of the homeowner.
The test kits used by our program are the charcoal canister devices (short-term testing) and the alpha-track detectors (long-term testing). The charcoal canisters provide relatively quick results and the alpha-track detectors provide a more accurate average of the Radon concentration in a specific area.
