WebSr-90 is β-decay and its daughter nucleus Y-90 is also β-decay.Since β-ray interacts with the coulomb field of the atomic nucleus, it radiates the secondary radiation, called bremsstrahlung [4, 5].Radiated γ-ray has a continuous energy spectrum (0.11 ~ 2.09 MeV).The radiation shielding analysis is focused on the bremsstrahlung γ-ray in this study.
