Radiation, Geiger Counter, METER SURVEY RADIAC No.2, 

MOD / Military Surplus 

Manufactured by E.K. Cole Ltd

Dated around 1955 - 70's, Cold War Period!

Measures Gamma - Detects Beta

Beta detection is accomplished by removing the base plate and a barrier plate inside. The unit was used by the Civil Defence Post War. Although referred to as Geiger counters, most CD devices were radiological survey meters capable of measuring only high levels of radiation that would be present after a nuclear event. Required 2X 1.5Volt 1X 9Volt and 1X 30Volt Batteries. The Radiac Survey Meter No 2 or RSM was a 1955 meter which counted the particles produced by radioactive decay.

Originally designed to monitor fallout after a nuclear attacks or reactor meltdowns

E K Company was set up as a result of early development work carried out by Eric Kirkham Cole on a high capacity condenser for early radio sets. The company EKCO as it became known was formally incorporated as E K Cole Limited in 1926. The premises were situated in Southend-on-sea from the very start. Up until the 1920s Eric had produced equipment suitable for use on Direct Current (DC) electricity, rather than the Alternating Current (AC).

1939 saw all work on domestic radios and TVs stopped as the company turned over its production capacity to war work. It had already built up a reputation for development work on radar for the Air Ministry. Production of radar related equipment was moved away from Southend, which was viewed as being too close to the coast and enemy action. During the war the company was involved in the research and development of various transmitting receiving sets.

After the war, the company returned to producing radio sets and televisions, as well as continuing to develop radar for commercial aviation use as well as radar ranging equipment for the Royal Air Force. Work on electrical equipment for the nuclear industry resulted in the company successfully manufacturing the first complete nucleonic instrumentation system for export to Australia, in 1957. In the same year the company  Ferranti Radio and Television Ltd, a wholly owned subsidiary to market receivers under the Ferranti trademark.

Potentially still in working order, but untested. However, when 2 x standard D / LR 20 1.5v batteries are fitting, the meter lights up and the meter moves, which is a positive outcome.
