In the new and improved radiation apparatus disclosed herein for inspecting tubular goods, a radiation detector is adapted to be received within a tubular member being axially translated along a selected inspection axis for receiving radiation from a radiation emitter facing the detector and mounted in a body rotating around the exterior of the tubular member. To assure that the detector will remain coaxially positioned within a tubular member with a minimum of erratic movements in relation thereto, the detector is supported by fixed, depending slides which are adapted to be interchanged with other slides as required to correctly position the detector. The ends of the detector housing are uniquely shaped to facilitate the insertion of the detector housing into a tubular member advancing along the inspection axis without reducing the speed of movement of the tubular member.
