A modular radiation detector (10) includes a scintillator module (12) containing a crystal (18), and an electronics module (14) containing a light sensing device (24) such as a photomultiplier tube (PMT), and an electronics package (26). The scintillator module (12) and the electronics module (14) are releaseably mechanically coupled, for example by means of mating threaded portions (132, 136) on each of the modules. The crystal (18) and the PMT are optically coupled via an optical window (70) in the scintillator module (12) and a removable gel pad (32) which is pressed between the modules (12, 14) as they are mechanically coupled together. <IMAGE> |
