Abstract
A method and device are provided for demounting in a radiation detector a photomultiplier tube the bottom of which is solely bonded with a scintillation crystal assembly by means of an elastic light transparent adhesive. A shearing tool is placed at the bond between photomultiplier tube and scintillation crystal assembly which is operated such that it shears the bond. Especially as a shearing tool a thread is placed around the bond such that it forms a noose. The thread ends have been wrapped around a rod. When twisting the rod the thread continues to wind around the rod thereby making the loop smaller and shearing the bond.
