Bremsstrahlung data in concrete shielding

Abstract

<span style="mso-bidi-font-size: 14.0pt" lang="EN-GB">Present work formulated the new method to evaluate the EB spectrum and hence Bremsstrahlung dose of beta nuclides (³²P, ⁸⁹Sr, ⁹⁰Sr/⁹⁰Y, ⁹⁰Y, ⁴⁰K, ⁶¹Co, ¹⁹⁹Pt, ¹⁶⁵Dy and ¹⁰¹Tc) in concrete. The Bremsstrahlung yield of these beta nuclides in concrete is also estimated. This estimated spectrum is accurate because it is based on more accurate modified atomic number (<i style="mso-bidi-font-style:normal">Z</i>_mod) and seltzer’s data where an electron-electron interaction is also included. Presented data in concrete provide a quick and convenient reference for radiation protection. The present methodology can be used to calculate the Bremsstrahlung dose in nuclear sheilding materials. It can be quickly employed to give a first pass dose estimate prior to a more detailed experimetal study.
