a MR eg ne pattern on the ground was due primarily to superposition of gashrocm cloud fallout on the stem cloud pattern; and the superposition can be attributed to the narrow cone within acting. The theory that a sisnificant fallout does not cose froa the stratosphere is not substentia- ted by the facts of BRAVO. he For future high yield shots, the forecest and observed winds for the first twenty-four hour post-shot period abould receive as auch exphesia as analyses made for shot tice. Pe ? with ATTOS: Evacuation took place in accordence ene>sency plan and without incident. Evacua- tice was not effected prior to detonation because no signifi- eent fallout was expected on inhabited ereas. e ° gewmee.
