    Abstract: A scintillator-camera system for determining uniformity of radiation emission from a radioactive source includes a cylindrical scintillation detector (22), the scintillation detector (22) having a central hole along the long axis and having a conical mirror (27) around the scintillator (22) to direct light emitted from the circumference of the scintillator (22) to a camera (21). The camera (21) is arranged to view the scintillation detector (22) so that light stimulated in the scintillator (22) by a radioactive source inserted in the central hole is detected by the camera (21), the camera (21) producing image data upon detection of light stimulated in the scintillator (22). The image data are adapted to be analyzed to detect non-uniformity in a radiation emission pattern from the radioactive source. The image from the thick scintillator (22) and surrounding conical mirror (27) provides information about both circumferential, i.e., radial, and axial emission non-uniformities in a single view of the radioactive source(s) or seed(s) within the thick scintillator (22).
