stakes, Sais . H x4 o Un ASoirith These materials would be used for measurement of the nuclear and thermal radiation as a function of distance. Distribution was carried out without difficulty and final preparations for test X-Ray s2 were completed by noon on X~Ray—minus-one, a The following is an estimite of results obtained from various a projects under TU 7.6.6 carried out during test X-Ray. These projects = were outlined elsewhere in this report (Ch 4, pp 20-21; Ch 6, pp 46-47) oe and are covered in detail in Annex "G", OpPlan 1-48, TG 7.6. pf Project K %.1-17/RS-1 -- Gamma Radiation vs Distance Exposed filns were recovered intact fron Muzin and Karinian Islands ~ (2200-1000 yds), Lost of the canpletely exposed films on Engebi were = destroyed due to ignition of the aluminum foil covering but a few which apo i had not been too greatly damaged were recovered and may provide occasional values, However, many films were recovered which had been given only small amounts of steel shielding (2") and these should be quite satisfactory for determining the gamma radiation as a function of distance , s after a slight correction has been applied, All films have been returned to Dr, Taylor at National Bureau of Standards for development and final results are not yet available. In Test Yoke a thin shield with an air space between it and the film was placed in front of the film badge in ve order to avoid ignition of the aluminum foil, An iS NY Project / — Jolel7/RS-2 ~ aN ‘ Gamma Radiation Shielding Films were recovered from all BuShips! steel plates and concrete ~ slabs and fran within four OCE structures, and most of the Yards and Docks structures, SL. - a 2 - Aly \. wai Sy ee es ome Larosean oe rt SE Ro RN RT NSEPS ALNe Ne ae Os gers AT» te < fag . aye toe xO 1 ON ttt 77
