Book Synopsis Attenuation of Gamma Radiation Through Two-legged Rectangular Ducts and Shelter Entranceways. an Analytical Approach by : A. B. Chilton
Download or read book Attenuation of Gamma Radiation Through Two-legged Rectangular Ducts and Shelter Entranceways. an Analytical Approach written by A. B. Chilton and published by . This book was released on 1961 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach is developed to permit determination of gamma radiation attenuation as it passes through two-legged rectangular ducts and shelter entranceways. The approach used employs the albedo concept for wall scattering and included correction terms necessary to account for the "corner lip effect." With appropriate simplifying assumptions, moderately simple engineering formulas are obtained. Actual use of the formulas requires better knowledge of differential angular albedo than is presently available; however, by assuming isotropic distribution of the albedo function, a very good comparison of experimental information with results calculated by this technique is obtained.

Download or read book The Variation of Dose Attenuation of Two-legged Concrete Ducts with Incident Gamma-ray Energy written by J. M. Chapman and published by . This book was released on 1965 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gamma-ray dose attenuation factors were measured in a 3-foot square and an 11-inch square duct using Au-198 (.412 Mev), Cs-137 (.662 Mev), and Co-60 (1.25 Mev) gamma-ray sources. Attenuation factors for given geometries were compared as a function of the incident gamma-ray energy. It was found that the attenuation factor decreases monotonically with increasing energy. Measured attenuation factors were compared with values obtained using a computer code based on the albedo concept. It was found that calculated attenuation factors are high by as much as g8 percent for Au-198 in the 11-inch duct. (Author).
Book Synopsis Dose Measurements of Gamma Radiation Streaming Through Concrete Ducts with and Without Lead Liners and Through Corrugated Steel Ducts by : J. M. Chapman
Download or read book Dose Measurements of Gamma Radiation Streaming Through Concrete Ducts with and Without Lead Liners and Through Corrugated Steel Ducts written by J. M. Chapman and published by . This book was released on 1968 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dosimeter measurements were taken in a 3-foot-square, two-legged concrete duct, with and without the presence of lead sheets covering the basic scattering areas in the corner, to determine the effectiveness of lead sheeting in reducing gamma radiation. For Co60 radiation, the lead sheets reduced the dose rate in the second leg of the duct down to 46% of the dose rate measured in the second leg of the duct without lead sheets, and for Cs137 radiation the reduction was down to 36%. Calculations were made to determine the effectiveness of the sheets in different size ducts, and comparisons were made with other methods for reducing radiation. Measured attenuation factors for a circular, thin-walled, corrugated steel duct were compared to values calculated by a simple computer program for a square, thick-walled steel duct. It appears that the computer code can be used to approximate attenuation factors for a corrugated steel duct. (Author).
