Ohio State University Fact Sheet Community Development 700 Ackerman Road, Suite 235, Columbus, OH 43202-1578 Radon CDFS-189-96 Thomas W. 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.

Return to Federal Citizen Information Center Home Page I f you're like most Americans, you spend much of your tim eindoors. Have you ever stopped to think about whether the air you're breathing at hiome is healthy? When you're at home do you frequently have headaches or feel nauseous or tired? Do you feel better when you leave the house? If you have these symptoms, or others listed in this booklet, your home's air quality may be the problem. Recent research has found that in homes across America, the quality of indoor air can be worse than outdoor air. That's because many homes are being built and remodeled tighter - some with improved ventilation system to provide fresh air exchange. We are using more products and furnishings containing compounds sensitive to some occupants. You don't have to be a building scientist to deal with the quality of air in your home. However, you should understand a few basics. to get you started. The "Healthy Indoor Air for America's Homes" project was developed to provide basic but comprehensive information to consumers to get a handle on indoor air quality. A major hazard is MISINFORMATION. Be informed. Request more information by contacting the resources listed on the back of this booklet.

Radon Noin puolet suomalaisen saamasta säteilyannoksesta on peräisin huoneilman radonista. Keskimääräinen radonpitoisuus suomalaisissa asunnoissa on noin 120 becquereliä kuutiometrissä. Se vastaa noin kahden millisievertin säteilyannosta vuodessa. Kaikkein tehokkaimmin vähennettäisiin suomalaisten keskimääräistä säteilyannosta pienentämällä huoneilman radonpitoisuutta. Asuntojen, työpaikkojen ja porakaivovesien radonpitoisuudet ovat Suomessa maailman suurimpia. Esitteet: Onko kodissasi radonia?

Huoneilmassa leijuvat radonin hajoamistuotteet kulkeutuvat hengityksen mukana keuhkoihin. Itse radonkaasu poistuu uloshengityksen mukana, mutta kiinteät hajoamistuotteet tarttuvat keuhkojen sisäpintaan. Keuhkojen saama säteilyannos lisää keuhkosyöpäriskiä. Suomessa todetaan vuosittain 2000 keuhkösyöpätapausta, joista radonin arvioidaan aiheuttavan noin 200 keuhkosyöpää. Radonpitoisen veden nauttimisesta aiheutuu säteilyä ruuansulatuselimille.

77. STUK - Radon radon. Ungefär hälften av den stråldos är helt frivilliga. Hur får man reda på, om det finns radon hemma eller på arbetet? Det enda http://www.stuk.fi/svenska/radon/

Radon Ungefär hälften av den stråldos en finländare får kommer från radon i inneluften. Den genomsnittliga radonhalten i finländska bostäder är ca 120 becquerel per kubikmeter. Detta motsvarar en årlig stråldos på ca 2 millisievert. Det effektivaste sättet att minska finländarnas genomsnittliga stråldos vore att minska radonhalten i inneluft. Radonkoncentrationerna i Finland i bostäder, på arbetsplatser och i vatten från borrbrunnar hör till de högsta i världen. Radon leder till lungcancer Radon är en luktlös, smaklös och osynlig radioaktiv gas, som sönderfaller så att sönderfallsprodukterna är fasta ämnen. Radonets sönderfallsprodukter, de så kallade radondöttrarna, svävar omkring i inneluften och hamnar den vägen i människors lungor. Själva radongasen försvinner när man andas ut, men de fasta partiklarna fastnar på lungornas inre slemhinnor. Risken för lungcancer ökar när lungorna får en stråldos av partiklarna. I Finland upptäcks årligen ca 2000 fall av lungcancer, och av dem tror man att radonet varit orsaken till ca 200 fall. Intagande av radonhaltigt vatten utsätter matsmältningsorganen för strålning.

More on Inquiries Service Printer Friendly Layout Physical Agents Radon in Buildings What is radon? Radon is an invisible, odourless, radioactive gas. It is formed by the disintegration of radium, which is a decay product of uranium. Radon emits alpha particles and produces several solid radioactive products called radon daughters. Some amounts of radon gas and radon daughters are present everywhere in the soil, water, and air. Particularly high radon levels occur in regions where the soil or rock is rich in uranium. Radon is emitted by radium in the ground, groundwater and building materials. It can enter the indoor air where it and its decay products accumulate in poorly ventilated areas. Harmful levels of radon and radon daughters can accumulate in confined air spaces, such as basements and crawl spaces. Radon daughters are inhaled with air and deposit in the lungs. The lung absorbs alpha particles emitted by the radon daughters. The resulting radiation dose increases the risk of lung cancer.
