Concrete structures for nuclear power plant or radiation medical facilities may be subjected to the gamma radiation conditions for a long period. This paper reports on the investigation into the fracture properties of concrete subjected to the effects of the gamma radiation. Three-point bending tests were con- ducted to measure the load versus crack mouth opening displacement (L-CMOD) curves. The initial cohesive stress and fracture energy were estimated by the inverse analysis of tension softening diagram calculated by the L-CMOD curve. The effect of the gamma radiation on the fracture properties was discussed.
