抄録

This equipment was installed at Ningyô-tôge Mine to determine the approximate grade of uranium ore by measuring radioactivity from the are in the mine tub and to separate at a given grade limit the are containing tub from the waste tub.<BR>The equipment is composed of eleven Geiger tubes which are placed with a given distance around the mine tub and of a counting and sorting electrical circuit. The radioactivity from the are is caught by the tubes and is counted by the counting circuit during a preset time, say, in 15 seconds. Consequently, the judgement of “go” or “no-go” on the are is indicated by the sorting circuit.<BR>With this device, it is possible to measure the radioactivity of all of the are in the mine tub by a given short time and to sort the are tub out of the waste tub.<BR>An experiment using this equipment has proved that the grade of uranium are is much correlative to the counts of radioactivity.<BR>The ability of this equipment regarding the separation has been proved to be satisfactory.
