A beta particle detector which scans a tape or wire passed through a pressurized area to be monitored is described. The tape or wire is passed through a hole in a tetraphenylbutadiene-in-polystyrene phosphor which is fitted in the end of a sleeve projecting into the pressurized area. The phosphor is optically connected to a photomultiplier tube in the sleeve by a methyl methacrylate guide. The photomultiplier tube may be removed and replaced in the sleeve without breaking the sealed pressurized area. (T.R.H.)
