Press Release ISBN Binding List Price Web Discount Price Add to Shopping Cart hardcover International Price The Safe Drinking Water Act directs the U.S. Environmental Protection Agency (EPA) to regulate the quality of drinking water, including its concentration of radon, an acknowledged carcinogen. This book presents a valuable synthesis of information about the total inhalation and ingestion risks posed by radon in public drinking water, including comprehensive reviews of data on the transfer of radon from water to indoor air and on outdoor levels of radon in the United States. It also presents a new analysis of a biokinetic model developed to determine the risks posed by ingestion of radon and reviews inhalation risks and the carcinogenesis process. The volume includes scenarios for quantifying the reduction in health risk that might be achieved by a program to reduce public exposure to radon. Risk Assessment of Radon in Drinking Water , reflecting research and analysis mandated by 1996 amendments to the Safe Drinking Water Act, provides comment on a variety of methods to reduce radon entry into homes and to reduce the concentrations of radon in indoor air and in water. The models, analysis, and reviews of literature contained in this book are intended to provide information that EPA will need to set a new maximum contaminant level, as it is required to do in 2000.

Tento plyn, resp. jeho projevy, je možné diagnostikovat a stavebními úpravami omezit jeho koncentrace v objektech na únosné množství. Z mìøení v minulých desetiletích bylo prokázáno, že naše republika, resp. Èeský masív, patøí k nejvíce "zamoøeným" celkùm v celé Evropì. Je to zpùsobeno vyšším zastoupením vyvøelých hornin v geologickém podloží naší republiky.

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. Esite: 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.

Named for the element Radium. Say what? Radon is pronounced as RAY-don History and Uses: Radon was discovered by Friedrich Ernst Dorn, a German chemist, in 1900 while studying radium 's decay chain. Originally named niton after the Latin word for shining, nitens, radon has been known as radon since 1923. Today, radon is still primarily obtained through the decay of radium. At normal room temperatures, radon is a colorless, odorless, radioactive gas. The most common forms of radon decay through alpha decay . Alpha decay usually isn't considered to be a great radiological hazard since the alpha particles produced by the decay are easily stopped. However, since radon is a gas, it is easily inhaled and living tissue is directly exposed to the radiation. Although it has a relatively short half-life , radon decays into longer lived, solid, radioactive elements which can collect on dust particles and be inhaled as well. For these reasons, there is some concern as to the amount of radon present within homes. Radon seeps into houses as a result of the decay of radium

NEW!! Radon in Alabama Newsletter, vol. 5 no. 3, April - June 2002 (PDF) What is Radon? Radon is a colorless, odorless and tasteless radioactive gas that occurs naturally in most rocks and soil. It is produced by the breakdown of uranium in soil, rock and water. Radon is harmlessly dispersed in outdoor air, but when trapped in buildings can increase the risk of lung cancer, especially at elevated levels. What is the Health Risk? According to the Surgeon General, exposure to radon is the second leading cause of lung cancer in the United States and is estimated to cause 15,000 to 22,000 of lung cancer deaths per year. Radon is not known to cause other illnesses or problems such as upper respiratory infections, colds or allergic reactions. Its only known health effect is an increased risk of developing lung cancer. However, as with those who smoke, not everyone exposed to high levels of radon will develop lung cancer, and the time between exposure and the onset of cancer may be many years.

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.

Radon Muggsopp Bygningsmaterialer Avgassing ... Priser på utmåling av din bolig eller ditt kontor. Radon og fare for lungekreft Radongass og lungekreft Alunskifer Radongass stammer fra nedbrytningen av naturlige radioaktive stoffer i berggrunnen. Tilnærmet alle boliger er belastet med noe radon. De høyeste nivåene av radon finner man i områder med alunskifer og til dels granitt. Norge er et av de landene i verden som er mest utsatt for radon. Økt fare for lungekreft er den sentrale konsekvensen for vår helse. Tette boliger Utviklingen de siste tiårene har gitt oss tette boliger for å spare energi. Høye konsentrasjoner av radon samles opp. Variasjonene fra bolig til bolig er store. Kjellere er mest utsatt, mens toppetasjene er minst belastet. Variasjonene fra time til time kan være betydelige. En langtidstest er nødvendig for å slå fast den nøyaktige radonkonsentrasjonen. Øyeblikkstester gir dårligre nøyaktighet, men kan vise hvor radon trenger inn i boligen. Kilder til radon Den vanligste måten radongass trenger inn på er gjennom sprekker eller rørgjennomføringer i kjelleren. Avgassing fra grunnvann kan også bidra. Det samme gjelder skifer og granitt som bygningsmaterialer.

Description : Radon was first discovered as the gas produced from radium as it decayed in sealed ampoules. It is colourless and odourless, and is chemically inert, but it is dangerous because it gives off alpha rays.
