What are the chemical and radiologic characteristics of radon? Rn), formed in the U decay chain, is the most important isotope because of its relatively long half-life of 3.82 days. The short half-life beta- and gamma-emitting decay products of Rn achieve equilibrium with the parent isotope within several hours. 2. Draw the 226Ra decay chain. Include the half-life and major emission type of each decay product. 3. What are Rn progeny? Why are they important? Radon-222 progeny is another name for the Rn decay products or Rn daughters. Radon-222 progeny rather than Rn gas deliver the actual radiation dose to lung tissues. The solid airborne Rn progeny, particularly

Location/Contact Search Annual Report 2003 Fields of activity of the institute Research program: For the topics of ongoing research both within the groups of the institute and in cooperation between these groups, see Research Groups and Topics Special programs: These are generally one-semester programs which are dedicated to varying topics from an applied science in which mathematical methods as represented in the institute are of interest, or to a methodological topic which is of importance to several problem classes from applied sciences. The aim will be that through intensive co-operation between representatives of the applied science and mathematicians, methods will be developed which will firstly further advance the applied science and secondly lead to interesting mathematical results and problems. At the beginning of each of these semesters, the topic shall be outlined and defined both from the applications and from the methods side in the course of an international meeting; a result of the meeting shall be a collection of topics of research on which work will be done in the following semester. In this work, both part of the institutes staff and guest scientists will be involved, who ideally will spend the whole semester at the institute. To a large extent, they will be representatives of the applied science, normally rather young Post-docs who are on leave from their institute, in some cases also specialists for mathematical methods which shall reinforce the methodological competence of the institute. The results of the co-operation shall be presented again about a year after the meeting in the course of a conference.

Lots More Information Shop or Compare Prices If you live in certain parts of the United States, you might be aware of the threat that radon gas poses. Radon gas is radioactive, and in tightly insulated houses it can accumulate to concentrations that pose a health threat. If you inhale the gas into your lungs, its decay can increase your chance of getting lung cancer. A study reported in 1990 by the National Safety Council estimated that about 14,000 deaths a year could be attributed to radon, and that the number could range from 7,000 to 30,000. In this edition of How Stuff Works , we'll talk about what radon is, how you can find it in your home and what the health risks are for it.

Radon gas, like carbon-14 gas, is completely natural. It forms during the decay of uranium-238, an element with a fairly interesting decay sequence (to learn more about decay sequences and radioactivity in general, see How Nuclear Radiation Works Start with a uranium-238 atom. This atom has 92 protons and 146 neutrons. It has a half-life of 4.5 billion years. When it decays it emits an alpha particle, leaving behind a thorium-234 atom. A thorium-234 atom has 90 protons and 144 neutrons. It has a half-life of 24.5 days. When it decays it emits a beta particle and a gamma ray, leaving behind a protactinium-234 atom.

Forbrugerrådets blad Tænk skriver: "Radon er en af de mest upåagtede sundhedstrusler i Danmark. Skønt vi kan trøste os med, at radonniveauet i vores huse generelt er lavere end i andre lande, regner de danske myndigheder ikke desto mindre med, at 300 danskere hvert år får lungekræft på grund af radon." Hver tyvende danske bolig indeholder for meget radon Undersøgelser lavet af Sundhedsstyrelsen viser at hver tyvende danske bolig indeholder for meget radon. Hvert år dør ca. 300 danskere af lungekræft som følge af radon i hjemmet. Radon er en naturligt forekommende radioaktiv luftart, der dannes af det radioaktive stof radium, der findes overalt i jorden. Radon findes primært i enfamilieshuse, og der er forskellige faktorer, der er afgørende for, hvor stor radonkoncentrationen er i vore boliger. Når vi indånder radonholdig luft optages radon i vores luftveje. Når stoffet nedbrydes udsender stoffet stråling, som skader cellerne i luftveje og lunger. Derfor er radon farligt for menneskers helbred. Læs mere her Hvad med dér hvor jeg bor?

Study Contact and Additional Radon Information May 25, 2000 THE UNIVERSITY OF IOWA Iowa City, Iowa 52242 UI study finds residential radon exposure poses a significant lung cancer risk IOWA CITY, Iowa Long-term exposure to radon in the home is associated with lung cancer risk and presents a significant environmental health hazard, according to a study led by researchers at the University of Iowa College of Public Health. The Iowa Radon Lung Cancer Study, funded by the National Institute of Environmental Health Sciences, included investigators from the UI, St. John's University in Collegeville, Minn. and the University of Kansas. The results are published in the June 1 issue of the American Journal of Epidemiology. From 1993 to 1997, the researchers studied 1,027 Iowa women 413 who were newly diagnosed with lung cancer and 614 "controls" ages 40 to 84 who had lived in their homes for the past 20 years or more. The women studied in both groups included smokers as well as nonsmokers. Women were studied because they typically have less occupational exposures to substances that may cause lung cancer, and historically have spent more time in the home. The researchers found that close to 60 percent of the basement radon concentrations for both the lung cancer cases (study participants with lung cancer) and the control group (participants without lung cancer) exceeded the U.S. Environmental Protection Agency action level for radon of 4 picoCuries per liter (pCi/L). The researchers found that 33 percent of living areas for the lung cancer cases, and 28 percent of the living areas for the control group, exceeded the EPA's action level of 4 pCi/L.

HOME FAQ MAPS RESEARCH What is radon, and why do we care about it? Radon is a naturally occurring radioactive gas that is produced by the radioactive decay of radium. Breathing high concentrations of radon can cause lung cancer Is it dangerous, and what can be done about it? For these answers, and more, visit the "Frequently Asked Questions (FAQ)" page. Should I test my house for radon? The Environmental Protection Agency says yes, everyone should test. But we, along with colleagues at Columbia University, have developed a web site that will help you decide whether to test , based on information about your home and your personal risk preferences. We suggest that you visit that site to get specific advice for your home. What did the LBNL high-radon project do? Predictions and maps Predicted distributions of long-term, living-area radon concentrations for nearly all counties in the U.S. Geology Quantified the extent to which different types of geologic information can be used to predict indoor radon concentrations.
