Radium What Is It? Radium Is a Radioactive Element That Occurs Naturally in Very Low Concentrations Symbol: Ra (About One Part Per Trillion) in the Earth’S Crust
Human Health Fact Sheet ANL, October 2001 Radium What Is It? Radium is a radioactive element that occurs naturally in very low concentrations Symbol: Ra (about one part per trillion) in the earth’s crust. Radium in its pure form is a silvery-white heavy metal that oxidizes immediately upon exposure to air. Radium has a density about one- Atomic Number: 88 half that of lead and exists in nature mainly as radium-226, although several additional isotopes (protons in nucleus) are present. (Isotopes are different forms of an element that have the same number of protons in the nucleus but a different number of neutrons.) Radium was first discovered in 1898 by Marie Atomic Weight: 226 and Pierre Curie, and it served as the basis for identifying the activity of various radionuclides. (naturally occurring) One curie of activity equals the rate of radioactive decay of one gram (g) of radium-226. Of the 25 known isotopes of radium, only two – radium-226 and radium-228 – have half-lives greater than one year and are of concern for Department of Energy environmental Radioactive Properties of Key Radium Isotopes and Associated Radionuclides management sites.

Naturally Occurring Radioactive Material (NORM VI) (NORM Material Radioactive Occurring Naturally Naturally Occurring Radioactive Material
Naturally Occurring Radioactive Material (NORM VI) Naturally Occurring Radioactive Material All minerals and raw materials contain radionuclides of natural origin. For (NORM VI) most human activities involving minerals and raw materials, the levels of exposure to these radionuclides are not significantly greater than normal background levels. However, certain work activities can give rise to signif- Proceedings icantly enhanced exposures that may need to be controlled by regulation. Material giving rise to these enhanced exposures has become known as of an International Symposium naturally occurring radioactive material (NORM). Historically, most regula- tory attention has been focused on the mining and processing of uranium Marrakesh, Morocco, 22–26 March 2010 ore, because such activities are a direct consequence of the radioactivity in the ore and form part of the nuclear fuel cycle. Over the past decade or two, however, more and more countries have introduced measures to reg- 1 ulate exposures arising from a wider range of natural sources. The NORM VI symposium, which was held in Marrakesh, Morocco, from 22–26 March 2010, provided an important opportunity to review the developments that had taken place during the three year period since the NORM V sym- posium in 2007. This period, which began with the publication of new radiation protection recommendations by the International Commission on Radiological Protection, was characterized by ongoing activities to revise international standards on radiation protection and safety. These Proceedings contain all 38 papers accepted for oral presentation and four rapporteur reports, as well as a summary that concludes with the main findings of the symposium. Text versions of 43 poster presentations are provided on a CD-ROM which accompanies these Proceedings. -
Radionuclides Notice of Data Availability Technical Support Document
Radionuclides Notice of Data Availability Technical Support Document March 2000 Targeting and Analysis Branch Standards and Risk Management Division Office of Ground Water and Drinking Water United States Environmental Protection Agency Prepared by: USEPA Office of Ground Water and Drinking Water in collaboration with USEPA Office of Indoor Air and Radiation United States Geological Survey Preface Under the authority of the Safe Drinking Water Act (SDWA) and its amendments, EPA sets drinking water standards for contaminants, which potentially pose a threat to public health via a public drinking water source. In 1976, EPA promulgated National Interim Primary Drinking Water Regulations (NIPDWR) for three categories of radionuclides: gross alpha emitters, radium 226 and 228 combined, and gross beta and photon emitters. The 1976 NIPDWRs for these radionuclides regulated: 1. gross alpha at 15 picoCuries per liter (pCi/L)(excluding radon and uranium); 2. radium-226 and radium-228 combined at 5 pCi/L; 3. and beta/photon emitters at a 4 millirem dose of radioactivity. The 1986 reauthorization of the Safe Drinking Water Act (SDWA) declared the interim standards for these radionuclides to be final National Primary Drinking Water Regulations (NPDWR). The 1986 amendment also required standards to be set as close to the maximum contaminant level goal (MCLG; the health goal) as possible. At that time, radionuclides did not have an MCLG. In 1991 (56 FR 33050), EPA proposed: < A Maximum Contaminant Level Goal (MCLG) of zero for all radionuclides; < A -
Playing Hickory Golf While You Piece Together a Vintage Set
CHAPTER 10 cmyk 4/11/08 5:13 PM Page 165 Chapter Title CHAPTER 10 Questions And Answers About Hickory Golf Q: How much does it cost to get started in hickory golf? A: You can purchase inexpensive hickory clubs for as little as $25 each. Obviously, these are not likely to be of a premium quality and will probably require work to make them playable. At Classic Golf, we offer fully restored Tom Stewart irons for about $150 each with a one-year warranty on the shafts against breakage. Our restored woods are about $250 each for the premium examples. So, a ten-club set with two woods would run $1,700. A 14-club set would be $2,300. This compares favorably with the purchase of a premium modern 14-club set where your irons are $800, your driver is $400, fairway wood $200, two wedges at $125 each, hybrid at $150, and a putter at $200 for a total of $2,000. Q: Can a beginner or high handicap golfer play hickory golf? A: Yes. That is how it was done 100 years ago! It can be an advantage starting golf with clubs that require a more precise swing. Q: Are there reproduction clubs available and are they allowed in hickory tournaments? A: Reproduction clubs are available from Tad Moore, Barry Kerr, and Louisville Golf. Every tournament has its own set of rules. The National Hickory Championship allows reproductions because pre-1900 clubs are so difficult to find and are very expensive. At the present time there are ample supplies of vintage clubs available for play, but this could change with the increasing popularity of hickory golf. -

His historical insight and passion for good writing have made my dissertation far better than it would have been otherwise. Whether his feedback was positive or negative, it was invariably accurate and always helpful. Thanks too to Bruce Hunt for providing me with critical avenues to explore and ideas to consider throughout the long process of this project’s conceptualization and writing. Michael Stoff’s example and advice have helped me become a stronger teacher, writer, and scholar. The other members of my dissertation committee, Jeffrey Meikle and Alan Kraut, also provided helpful suggestions for improvements in both substance and style.
