Radiation detector, 'Portable Contamination Meter Type P.C.M.5', metal, made by Nuclear Enterprises Ltd, Edinburgh, Scotland, 1980
The detector has a body encased in a yellow metal housing. The front of the unit has a blue metal handle, a grey dial, and a 'counts per second' meter window. There are two probe attachments; both have yellow metal bodies with a square head. They are connected with a black electrical cord.
The rate meter is designed to be used with different types of scintillation and GM (Geiger-Mueller) probes for monitoring all types of radiation. The detector in the probe consists of a plastic phosphor scintillation plate coated on one face with zinc sulphide. A tin layer of aluminised polycarbonate covers the detector; to prevent this layer being damaged, it is covered by a metal grille. The window area is 49 square cm. The instrument can be used in direct reading mode or as a counter. The rate meter also has a sound alarm.
