Bremsstrahlung Yield Calculation

Bremstrahlung from secondary electrons and positrons created by pair creation has been treated by a simplified method which neglects electrons/positrons movements inside materials using a discrete ordinate code. Bremsstrahlung from recoil electrons after Compton scattering must also be considered for precise calculations of the photon dose inside materials. It is required to provide data concerning the double differential bremsstrahlung yields after pair production and Compton scattering for a discrete ordinate code. The EGS4 user code, ucbrempc.mor, was written for this purpose. In KEK Internal 2002-5, outlines of ucbrempc.mor and the input data are presented together with the calculated results for lead.
