Book excerpt: Monte Carlo calculations were carried out in great detail on the reflection properties of concrete for fast neutrons. The results are presented for the differential angular dose albedo for various incident-beam conditions and touches upon some of the other distributions calculated. The following formula represents the calculated differential angular dose albedo to better than 10% for about 95% of the values obtained and can be used to extend the results to the entire hemispherical range for both incident and reflected neutron velocity vectors. A comparison of the fast-neutron angular dose albedo calculations weighted by an incident spectrum previously measured at the Tower Shielding Facility with the results of a series of dose albedo measurements performed at the TSF shows a root mean square deviation from 147 combinations of the incident and reflected angles of 3.1%, with the largest single deviation being 9%. This excellent agreement shows that existing cross sections are adequate to calculate differential albedos to a high precision.

Download or read book Calculations Using the Albedo Concept of Thermal neutron Fluxes Epicadmium neutron Fluxes and Fast neutron Dose Rates Along the Center Lines of Square Concrete Ducts written by R. E. Maerker and published by . This book was released on 1967 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monte Carlo calculations that use the albedo concept and a particularly demanding source geometry and spectrum were carried out to determine subcadmium- and epicadmium-neutron fluxes and fast-neutron dose rates along the center lines of one-, two-, and three-legged square concrete ducts open on the source end. Secondary gamma-ray dose rates arising from the capture of neutrons in the duct walls were also calculated. The calculations used previously reported albedo data that are differential in both the reflected angles and the reflected energy. A comparison of the calculated neutron fluxes and dose rates with those obtained in geometrically identical experiments conducted at the Tower Shielding Facility shows agreement generally within 25 percent through five orders of duct attenuation. The results thus place on a firm foundation the method of treating neutron transmission through large-sized ducts as a multiple-reflection phenomenon describable by the differential albedo properties of the walls. The conclusion is also reached that wall-capture gamma-ray dose rates arising from capture of thermal-neutrons and the dose from the thermal neutrons themselves (whether due to an epicadmium source or a subcadmium source) can comprise a very important part of the total absorbed dose rate in tissue at locations deep inside a multilegged duct.
