  • Apparatus for and methods of remotely monitoring outputs of Geiger-Mueller tubes
    Patent number: 4251810
    Abstract: Apparatus for and methods of remotely monitoring outputs of Geiger-Mueller tubes including cables for connecting individual Geiger-Mueller tubes to a central monitoring station wherein electronics for sensing the output of each tube is located at the central station rather than juxtaposed with each tube. The electronics are used to trigger individual alarms and a general alarm whenever radiation levels sensed by the Geiger-Mueller tubes pass a predetermined threshold. The apparatus and method are especially useful for monitoring levels of materials in hoppers, or the like, by sensing the impingement of or absence of beams of radiation on Geiger-Mueller tubes.
