In this work,concrete with different percentage leads was used to study gamma-ray shielding properties. The gamma-rays from ~(137)Cs and ~(60)Co sources were detected by Nal(Tl) detector and analyzed by multi-analyzer. Linear attenuation coefficients and compressive strength(kg/cm2) of concrete specimens were conducted.Results show that the concrete at the 90% weight ratio of lead to cement can be suitable for shielding gamma-ray.
