(U) Neutron data were obtained by CWL- for Shots Fig, Hamilton, and Humboldt, and reported in Reference 62. (U) The gamma and neutron data for Shots Lea, Mora, and Socorro were obtained by ORNL and reported in Reference 63. The gamma dosimeters exposed were tetrachloroethylene chemical dosimeters and AgPO, glass rods in the ORNL aluminum "Beer Mug" shield including natural lithium shielding. The gamma 2nd neutron data were presented as "normalized" data for Shots X, Y, and Z (Lea, Mora, and Socorro). The appendix to Reference 63 provides the clues necessary to correct the normalized data to actual data for the actual shot. The "scale factors" reported for the neutron data were incorrect. & private communication (Reference 64) from the authors of the report states that the reciprocal’ of the neutron "scale factors" should be used. (JU) The gamma data are presented in Tables 3.113 thru 3.113. Graphs of gamma-dose-times-slant-range-sguared versus slaint-rance are snown in Figures 3.22 thru 3.87. 3.13 OPERATION SUN BEAM (U) Cceration Sun Beam was conducted at NTS in July 1962. The opera- tion consisted of four shots of small-ylield weapons close to the ground. A summary of the shot information is given in Table 3.119, and the meteorological conditions at shot time are presented in Table 3.120. (JU) Tre USANDL measured the initial gamma dose for the four shots (Reference 11). The detectors used were film in NBS holders, glass micrcdosimeters in tin-tantalum-teflon holders, cobalt-glass plstes, calcium fluoride thermoluminescent dosimeters, and formic-acid chemical dosimeters. The formic-acid dosimeters yielded no usable data and the thermoluminescen dosimeters were generally lower by a factor of three as compared to the other three dosimeter systems. Only a few thermoluminescent dosimeters were exposed, and the results are not presented in this compilation. The dosimeters were exposed mainly in steel pipe nipples which were attached to pull-out recovery lines. No residual radiation corrections are necessary in view of the early recovery of all dosimeters. Protection from thermal neutrons wes, in many cases, provided by a shield of lithium-6. The cobsait plates which were not protected by Li yielded cata which are suspect Since the thermal-neutron correction is very large and not accurately known. WL
