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