Abstract

Abstract

In nuclear industry some components will be radioactive from neutron induced activity. Radiation safety should be taken into consideration when the sample is measured. Considering the neutron diffraction technique and radiation safety, a method for measuring the radioactive sample is proposed and a shielding assembly is designed and fabricated. Using this assembly, residual stress of the radioactive sample can be measured within a safe radiation environment.
