Radiation shielding re design,calculation and verification for the capacity expansion and technology upgrading of an electron accelerator building were conducted. Technological upgrading program involves accelerator up gradation (from μA level to mA level),installing sideroom as a maze for mounting rotation type conveyer, and adding the built in local shielding concrete block in the maze to intensify shielding ability. Under operational conditions of the re designed accelerator, the resulting environmental radiation level coincides with the calculated results.
