Project No: 2.8a - Rocket Fallout Sampling it will be lowered to the lagoon by parachute. The filter head will incorporate a radio transmitter, dye marker, and a Sonar transducer to assist in recovery. Location and recovery will be accomplished by both aircraft and surface vessels, after which the units will be shipped to the ZI for analysis. Each sample will be analyzed for approximately 10 selected isotopes. For the land surface shot, sample analyses will permit integration of a given isotope activity and thus allow separation of the local fallout (large particles) from the world-wide fallout (small particles). Analysis and results of this Project will be closely correlated with those of Project 2.8b. & Special Requirements: 1. One land-based and one barge-based surface burst or ay 2. No aircraft should pass in the vicinity of the rocket trajectories from H/5 until #430 minutes. . 3. Vertical wind structure must be known but it does not represent a mandatory condition for firing. 4, One destroyer, two or three light aircraft, one crash boat with air/ground comminications, and several smaller surface craft required for location and recovery of filter heads. 5. Incorporation of a suitable tracer in the land-based device, to allow correlation between the close-in measurements obtained by this Project and the several continuing world-wide fallout programs. Construction: Twelve rocket launching pads for each shot. permit maximum use of same pads for both shots.
