http://www.nap.edu/catalog/6287.html

Extractions: 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.

Extractions: Mission Statement: Radon Home Measurement and Mitigation (RHMM) performs radon testing of single and multi-family homes as well as radon testing in commercial or business locations, provides radon mitigation services and delivers radon education to interested groups and the public. RHMM also helps with any radon issue emerging during real estate transactions , helping real estate brokers, buyers and sellers to understand and deal with what may be a serious environmental health issue in a home. Our goal is to identify those places that represent a high radon exposure to the general public in residential, commercial and business environment and, after verification of an increased health risk, to fix the problem.

Extractions: 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? (pdf) Luonnonsäteilyyn liittyvä tutkimustoiminta Radon on hajuton, mauton ja näkymätön radioaktiivinen kaasu, joka hajoaa kiinteiksi hajoamistuotteiksi. 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

Extractions: 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. 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.
Radongass Og Fare For Lungekreft Ved Radon I Boliger

Extractions: Priser på utmåling av din bolig eller ditt kontor. 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.
