Monte Carlo Anaylsis of X-Ray and Gamma-Ray Transition Zone Dose and Photo-Compton Current.

Abstract

The POEM Monte Carlo electron transport code has been used to calculate dose and photo-Compton current distributions near interfaces between dissimilar materials irradiated by x-rays and gamma-rays. The calculations were performed for a planar gold-aluminum interface irradiated by 300 kVp and 1000 kVp x-ray bremsstrahlung spectra, a Co60 gamma-ray spectrum, and 30, 100, and 200 keV monochromatic x-ray spectra. For the monochromatic x-ray spectra several angles of x-ray incidence between 0 and 85 degrees with respect to the interface normal were used. The results of the dose distribution calculations for the x-ray brem strahlung spectra are compared with the unpublished data of Wall. The results for the Co60 gamma-ray spectrum are compared with the published data of Wall and Burke.
