This book was released on 1998 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report for DOE Grant DE-FG03-94ER6178, covering a performance period of 1 January 1994 through 31 December 1997. The DOE award amount for this period was $547,495. The objective of the project as stated in its proposal was {open_quotes}to improve our understanding of the physical processes controlling the concentration of radon, thoron, and their progeny in the atmospheric environment.{close_quotes} The original project was directed at developing underlying science that would help with evaluation of the health hazard from indoor radon in the United States and implementation of corrective measures that might be employed to reduce the health hazard. As priorities within the Office of Health and Environment (OHER) changed, and the radon research program was phased out, emphasis of the project was shifted somewhat to be also relevant to other interests of the OHER, namely global pollution and climate change and pollution resulting from energy production. This final report is brief, since by reference it can direct the reader to the comprehensive research publications that have been generated by the project. In section 2, we summarize the main accomplishments of the project and reference the primary publications. There were seven students who received support from the project and their names are listed in section 3. One of these students (Fred Yarger, Ph. D. candidate) continues to work on research initiated through this project. No post-docs received support from the project, although one of the co-principal investigators (Dr. Piotr Wasiolek) received the majority of his salary from the project. The project also provided part-time support for a laboratory manager (Dr. Maryla Wasiolek). Section 4 lists chronologically the reports and publications resulting from the project (references 1 through 12), and the Appendix provides abstracts of major publications and reports.

Book excerpt: This report covers progress under the current funding period Jan. 1, 1991 to Jan. 1, 1992 and presents the continuation proposal for Jan. 1, 1992 to Jan. 1, 1993. The previous progress report was submitted in May 1990, so activities during the last half of 1990 will also be included. Major activities over the last year have centered on the study of disequilibrium of radon progeny near the earth's surface and the sources of thoron in indoor air. In addition, we have carried out supplemental measurements of radon sorption coefficients in porous materials focusing on the physical mechanism of sorption.

Book excerpt: The radon and thoron progeny plate-out characteristics of several materials have been investigated in both large and small radon/thoron test facilities.Discs were made up of different materials such as metals, plastics, filtermaterials, fabrics, and powders. Plate-out studies were conductedpreferentially at low relative humidity and low aerosol concentrations.Significant differences in the surface alpha-activity were found betweendifferent materials. This work is relevant to the determination of radon andthoron progeny deposition velocities on, and attachment rates to, largesurfaces.

This book was released on 2015-02-02 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhalation of the short-lived radon and thoron decay products in homes, at work places and in the outdoor atmosphere, yield the greatest amount of the natural radiation exposure of man. Radon is known to present a risk of lung cancer when it, or rather its decay products are inhaled. For this reason, it is of great importance to determine concentrations of radon, thoron and their progeny in a room. For that purpose extended Jacobi's room model for three modal distribution of attached radon progeny is introduced. The parameters of Jacobi room model were determined by modeling radon and thoron progeny as Brownian particles, where indoor airflow is neglected. In case of turbulent indoor airflow, deposition velocities of unattached and attached radon progeny were presented as functions of friction velocity. Influence of aerosol characteristics on deposition rate of attached radon progeny and attachment rate in turbulent airflow was investigated in this monograph. It was shown that there is correlation between deposition rates and ventilation rate.

This book was released on 2016-08-11 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews all the major research accomplishments and summarizes the different applications of radon. It serves as a solid reference book for researchers who are interested in the U-series radionuclides and noble gases as tracers and chronometers. Radon has been widely utilized as a powerful tracer to quantify a number of processes that include gas exchange rates between air and water, submarine groundwater discharge in coastal waters, water exchange between rivers and lakes, ocean circulation, hydrocarbon and uranium exploration. It is also used as an atmospheric tracer for the identification and quantification of air masses and as a tool for earthquake prediction, etc. A significant portion of the book presents state-of-the knowledge on indoor-radon-related health issues. Applications of the decay-series of Rn-222 are presented in a chapter. It serves as a reference and a state-of-the-art resource for researchers who want to learn the different applications of radon in Earth systems.

Download or read book Radon Measurements By Etched Track Detectors - Applications In Radiation Protection, Earth Sciences written by Saeed A Durrani and published by World Scientific. This book was released on 1997-06-09 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to radon gas, which is present in the environment naturally, constitutes over half the radiation dose received by the general public annually. At present, the most widely used method of measuring radon concentration levels throughout the world, both in dwellings and in the field, is by etched track detectors — also known as Solid State Nuclear Detectors (SSNTDs). Although this is not only the most widely used method but is also the simplest and the cheapest, yet there is at present no book available on the market globally, devoted exclusively or largely to the methodology of, and dealing with the results obtained by, the SSNTD technique. The present book fills this important gap in the coverage of radon measurements. Individual chapters of the book are contributed by some of the most prominent and active research workers in the world in the SSNTD discipline as well as in the field of radon measurements. A detailed breakdown of the contents of the book is shown below together with the name(s) of the author(s) of each chapter.
