films that did drop indicated much smaller deses than those films which remained above ground. Although the tire of dropsing is unknown, the films might reasonably be assumed to have dropred before the arrival of fallout. Only the dropped-film data are presented with error limits wnien do not include the error due to dropping time. No neutron corrections are presented since the neutron flux was negligible.

All film badges Located from 700 to 1709 yards from ground zero were destroyed; the rest were recovered the day artee the snot. Survey readings indicated that residual activity was negligibie. All gama stations for both shots were on land. (U) Reference 13 gives some gold and sulfur data for the two snows. These data were extrapolated to the slant ranges of interest (U) The gamma data for both shots as well as the neutron for Shot King, are presented in Tables 3.45 and 3.46.

The operation consisted of 11 detorations highlighted by Shot 10, which was an atomic weapon fired from a cannon. The pertinent she information and meteorological data are given in Tables 3.47 and 2. LS respectively. It should be noted that in some of the WT reporss For this overation, the order of Shots 5 and 6 and Shots 8 and 9 was reversed Table 3.47 lists the date of detcnation. shot numbers strictly according to chronolsg gical UXS-ROTInitial gamma measurements were made by LASL (Reference 35) for Shots 5, 6, 10, and 11 and by SCEL (Reference 36) for Shots 1, 2, 3, 5, 6, 7, 8, 9, and 10. The SCEL gamma detectors consisted of five film types encased in NBS holders and attached to aluminum staxes assumed to be 1/4-inch thick. The film range was from 0 to 12,000 r. The detectors were recovered approximately 3 hours arter detonation. No azimuth is given for Shots 1, 3, 6, and 9, and no mention is made of corrections 32
