The dose gradient distributions of 60 Co γ rays in silicon at and near the interfaces between silicon and various materials were measured In the case of silicon adjacent to a high atomic number material
a dose enhancement effect was observed at the interface Dose gradient distributions were also calculated with a semiempirical electron transport equation based on the mechanisms of the Compton
photoelectric and Auger effects of γ-rays and secondary-electron transportation Good agreement was obtained between experimental and calculated results
