Order number 940406-165953-13 -001-001 page 50 set 5 with 341 of 341 items measured by rate of fireball growth measurements, and is described in the section entitled Fireball Determination of Total Yield prepared by Dr. Lewis Fussell of Edgerton, Germeshausen and Grier, Inc. The fission yield was to be determined by a radiochemical method and is described in Chapter III prepared by Dr. Roger Batzel of the University of California Radiation Laboratory. This 801. demonstration shot, designated Pinon, was cancelled on July 26, 1958. However, because the techniques described here had not been published previously it was considered desirable to publish the handbook.
