Spear, W G

The instrument was developed to provide an efficient, sensitive, reliable method of determining the extent of radioactive contamination on the bands, shoes, and clothing of personnel employed at the Hanford Atomic Products Operation, General Electric Company, Richland, Washington. The instrument can simultaneously detect and indicate radioactive contamination levels for alpha and beta particles and gamma photons which are produced by disintegration of radioisotopes. The instrument replaced, in one unit, two separate instruments of vacuum tube types designed for the same purpose. With the new instrument, complete personnel contamination determination is accomplished in less than one- half the time previously used. The new instrument has more than twice the detection sensitivity of either of the previous vacuum tube instruments. Multiplier phototubes and scintillating crystal detectors are used in the new instrument to achieve a reliability not obtainable with the air proportional chambers and Geiger-Mueller tubes used for alpha and beta-gamma detecting, respectively, in the two older instruments.
