Abstract: 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 (Zmod) 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.
