that there were discrepancies in gamma dose between the tested badge and the standard Task Unit 7 badge. 6.3 OPERATIONAL EVALUATION OF INDIRECT-BOMB-DAMAGE ASSESSMENT In project 6.1, the Strategic Air Command continued evaluation of interim indirectbomb-damage-assessment (IBDA) procedures and indoctrination of air crews in these procedures. The interim IBDA capability used airborne navigation-bombing radar and camera systems to obtain radar-scope photographs of the detonations, from which IBDA data could be extracted. Three B-50D aircraft were involved on six shots —a total of 18 missions. Excellent radar-scope photographs were obtained on all except two of the missions, and equipment TT TT T y T .

Because there were no air drops, information on techniques for radar-scope photography with the equipment on a strike aircraft was not obtained. Table 6.7 presents aircraft positions relative to site zero for the various shots. One airoraft aborted on Shot 4 and another on Shot 5, resulting in 16 successful missions for IBDA purposes. In addition to the IBDA missions, one B-$0 recorded radar returns in the vicinity of site zero for 10 to 15 minutes after shot time for Project l.ic. Examples of the photographs obtained are shown in Figures 6.9 and 6.10. For a surface detonation, the burst clearly shows as a horseshoe-shaped configuration during the e8
