In the hold, the mijor portion of the recorded dose is estimated to have been due to backscattered radiation from airborne and deposited activity. According to Ref. 41, the highest estimates of water contribution were obtained during participation in Shot Tewa, which ie classified as a land-surface, rather than a water-surface shot. At Tewa, water contribution to both dose and dose rete was estimated to have been less than 11% in the lower hold where the 10 hr recorded dose was about 1 r, while the 10-hr deck dose was about 25 r, and the 10-hr dose in the water was about 3 r. It was further estimated that rad- jation from the water contributed less than 1% of the total deck dose. C: ee nee ee on rs 17-101 ee ren “To or
