Abstract

An irradiation target is formed into a sphere. The spherical irradiation target can be iridium metal containing natural or enriched iridium. The radiation source can be manufactured by manufacturing a spherical irradiation target, accommodating the spherical irradiation target in a rotating capsule, and rotating an axial flow impeller by a downward flow of a reactor primary coolant, whereby the rotating capsule is rotated. This radiation source provides an improved nondestructive inspection image having a high geometric resolution, and has no radiation source anisotropy and also has high target recyclability.
