The 5-year study was performed in Iowa and the participants were women throughout Iowa who lived in their current home for at least 20 years.  Over a thousand Iowa women took part in the study.  Four hundred and thirteen of the participants were women who had developed lung cancer, the remaining 614 participants were controls who did not have lung cancer.  The study was limited to women, because they historically tend to spend more time at home and they have less occupational exposure to other lung carcinogens. The epidemiologic study was performed in Iowa for several reasons. Iowa has the highest average

Apache Cochise Coconino Gila ... Yuma HOME RADON SURVEYS PHASE I AND PHASE II SUMMARY PHASE I AND PHASE II SUMMARY The Arizona Radiation Regulatory Agency (ARRA), in cooperation with the U. S. Environmental Protection Agency (EPA), initiated a program to measure radon concentrations in homes. The survey was conducted in response to the growing concern about potential health risks associated with indoor radon exposure. The primary goal of the home indoor radon survey was to determine the statewide distribution of radon in homes and identify areas of potentially high radon concentrations. During the winter and spring of 1987-88, ARRA and EPA conducted Phase I, a population-based home radon survey in Arizona. ARRA completed a follow-up, Phase II, during the winter and spring of 1988-89. The state legislature provided funds for the purchase of laboratory equipment, charcoal canisters, salaries for part-time employees for Phase I, and miscellaneous administrative expenses. Without these funds, the Agency could not have participated in the EPA survey or accomplished Phase II.

When the issue of radon first gained national attention in the early eighties, Tennessee immediately responded by establishing this statewide program. Originally, the function of the program was to educate, assist, and conduct outreach on the health hazard of radon and the various issues associated with that hazard. That was over fifteen years ago and the program's function has changed and expanded considerably. Today the radon program is still a statewide program. Outreach, education and assistance are still our primary functions. In addition, the program sponsors and conducts consistent and professional radon training in the areas of measurement, mitigation, schools testing and mitigation. It conducts scientific research on radon in Tennessee and how it relates to geology.

Blaine Radon is a colorless, odorless, tasteless gas that occurs naturally in most soils. Although you may not be aware of its presence, radon is a substance that poses the potential for lung cancer when a person is exposed to high levels over long periods of time. The Environmental Protection Agency (EPA) estimates that radon causes between 7,000 and 30,000 lung cancer deaths per year in the U.S., making it the second leading cause of lung cancer behind smoking. Radon exposure has also been shown to increase the risk of lung cancer among smoker. This fact sheet describes how radon forms in soils, how it infiltrates our living areas, how you can detect it, and what measures you can take to reduce your exposure to it. What is Radon? Radon-222 is a radioactive gas that is produced by the decay of uranium-238. which is found in varying degrees of concentration in most soils, in rock, and in ground water. As uranium-238 decays, radon-222 is formed. It, in turn, decays into various particles which can be inhaled in the air we breathe. Most of the time radon enters the lower levels of buildings through cracks in foundations or openings around pipes. Once inside, it is free to move about, and dissipates as it does so. For this reason, concentrations are usually higher in lower levels of buildings as compared to upper levels. After the energy crises of the 1970s, some experts argued that advances in building construction to conserve energy made it more likely that radon concentrations could be elevated in doors. Studies undertaken over the past decade however, have not substantiated this claim. Radon levels have not been found to be higher in well insulated homes. Thus concern about radon should not prevent anyone from taking steps to making living quarters more energy efficient.

@import url(/styles/advanced.css); Français Contact us Help Search ... Radon Radon Radon is a radioactive gas found naturally in the environment. It is produced by the decay of uranium found in soil, rock or water. Radon is invisible, odourless and tasteless, but emits ionizing radiation which can cause cancer. Because radon is a gas, it can move freely through the soil enabling it to escape to the atmosphere or seep into buildings. When radon escapes from the bedrock into the outdoor air, it is diluted to such low concentrations that it poses a negligible threat to health. However, if a building is built over bedrock or soil that contains uranium, radon gas can be released into the building through cracks in foundation walls and floors, or gaps around pipes and cables. When radon is confined to enclosed or poorly ventilated spaces, it can accumulate to high levels. Radon levels are generally highest in basements and crawl spaces because these areas are nearest to the source and are usually poorly ventilated. Water from some deep wells may contain dissolved radon. This can lead to exposure by either drinking the water or inhaling the radon that has been released to indoor air when that water is agitated (e.g. showering, washing clothes or cooking). While drinking water that contains radon has not been shown to be harmful to health, the additional radon released to the air may increase the inhalation hazard.

Radon and Drinking Water from Private Wells Download PDF version formatted for print (98 KB/2 pages) What is radon? Radon is a radioactive gas.  It occurs naturally and is produced by the breakdown of uranium in soil, rock, and water.  It can also dissolve into our water supply.  How can I be exposed to radon? Radon typically moves up from the ground to the air and into your home through cracks in the foundation.  Radon gas can also enter the home through well water.  As you shower or use your well water for other household tasks, the gas can be released from the water into the air. Where and how does radon get into drinking water? While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the foundation, 30 to 1,800 deaths per year are attributed to radon from household water.  Showering, washing dishes, and laundering can disturb the water and release radon gas into the air you breathe. What are the symptoms of radon exposure?

FAQs Key Functions Infectious Diseases Radiation Emergency Response Business Activities Radon HPA radon detector pack - order securely online Radon is a natural radioactive gas. You cannot see, hear, feel or taste it. It comes from the minute amounts of uranium that occur naturally in all rocks and soils. Radon is present in all parts of the UK, although the gas disperses outdoors so levels are generally very low. We all breathe it in throughout our lives - for most UK residents, radon accounts for half of their total annual radiation dosage. However, geological conditions in certain areas can lead to higher than average levels. Some of the highest radon levels have been found in the southwest, but levels well above average have been found in some other parts of the UK. Exposure to particularly high levels of radon may increase the risk of developing lung cancer. The HPA has advised that indoor radon above an Action Level of 200 becquerels per cubic metre should be reduced. Most homes in the UK have fairly low radon levels, with an average of about 20 becquerels per cubic metre. The HPA conducts radon surveys for government departments, local councils, other organisations, and private householders.

Breathing home indoor radon causes nearly one hundred times more deaths each year than carbon monoxide poisoning. Radon is the second leading cause of lung cancer behind smoking. Some 20,000 people will die this year due to breathing too much radon without even knowing it. Responding to this danger, EPA is joining state, local, and tribal governments, community groups, public health organizations, and industry in designating January as National Radon Action Month, to raise public awareness and promote actions reducing these risks. "In our national drive to reduce greenhouse gases by making our homes greener, we shouldn't forget that they can't truly be green without being safe places for people to live," said Marcus Peacock, EPA's deputy administrator. "It's remarkably easy to protect our loved ones by testing for radon and building new homes with radon-resistant features that allow everyone to breathe freely and safely." As part of Radon Action Month, EPA has released a public service announcements featuring Fuad Reveiz, a member of the National Association of Home Builders and former NFL Pro Bowl place-kicker.
