SHOT 2 Only one station, George, collected enough fallout to be analyzed. The small fraction NMD's were 12.6 and 10.7 » for the 2-hr and 12ehr collectors, respectively. Not enough of the large fraction sample was collected to be analyzed. It appears (Sect. 3.3.2) that these particles were largely remains of Shot 1 fallout which had been redistributed during Shot 2. SHOT 3 The small fraction NMD's ranged from 9.4 p to 20.0 ps3 large fractions varied from SHOTS 4 AND 6 77 p to 127 pe Not enough radioactive material was collected from these two shots to be analyzed for particle size distribution. There was not enovgh fallout material in each collector interval for a meaningful analysis; so the fallout from all intervals in each collector was mixed together and analyzed. The only timing intervals which can be compared are the entire cycling times of each collector. On the basis of these cycles (2-hr and 12-hr) there is no trend of particle size with time after shot, within the limits of sampling time. Neither is there a trend of particle size with distance or direction from ground zero within the limits of the area covered by the collectorse The behavior of the cloud, which is discussed in Section 3.402, is believed to account for the lack of trends of particle-size data. The particle-size data obtained indicates that the Shot 1 cloud and the Shot 3 cloud particles were both fairly homogeneous within the limits of the area sampled. Lack of data from Shots 2,4, and 6 pre~ clude any statements about the particle size distribution character= istics from these shots. A difference was noted between the radioactive particle-size distributions of Shot 1 and those of Shot 3. The samples collected from Shot 1 were found to have 20 per cent of the particles under 5 p, which was 24 times as many as those collected from Shot 3 (Table 3.14) TABLE 3.13 - Shots 2 and 3 Radioactive Particle Analysis Results Shot 2 2 3 3 3 3 3 3.
