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.

An example remote control for a radiographic source includes: a forward cable section configured to extend into and through a radiographic source housing, to expose a radiographic source to an exterior of the housing, and to retract into and through the radiographic source housing to retract the radiographic source into the radiographic housing; a drive cable section coupled to the forward cable section; and a drive gear configured to extend the forward cable section by driving the drive cable section in a first direction, and to retract the forward cable section by driving the drive cable section in a second direction, wherein the forward cable has a smooth exterior surface to have a lower friction than the drive cable section while traversing the radiographic source housing.
