The data from this project are presented to indicate the approximate magnitude of the residual- gamma radiation to be expected from different types of nuclear devices. It is felt that with the exception of Shot Cherokee (for which insufficient data were obtained to form definite conclusions) the objectives of the project were met. - In the case of Shot Cherokee, the burst point was approximately 4 to 5 miles in the downwind direction away from the planned ground zero; this resulted in no downwind stations to document residual radiation from fallout. The ground zero for Shot Tewa was moved from its planned location off Site Dogt to a location approximately between Sites Charlie and Dog. It was therefore necessary to improvise stations at available locations on the man-made islands and the reef be45
