Appendix B RADIOCHEMICAL DATA TABLES Tables B.1 through B.6 contain a compilation af radiochemical data for all the samples collected by project aircraft. The samplers are identified by the aircraft number. The letters R or L placed next to the aircraft number indicate that sampling units toward the right or left side of the aircraft were used. The single rocket sample obtained is also included. The analytical results are tabulated separately for the gas and particulate samples from the three shots. Data on the particulate material is divided into three groups, namely, gross cloud samples, size~separated cloud samples, and fallout samples. In each table, the results are arranged in the order of increasing time of collection. The following general remarks will serve to clarify certain entries in the tables: 1. All fission values based on Mo™ in the particulate sample tabulations have been normalized to a LASL K-factor of 2.50 x 10°. This factor gave approximately the correct number of fissions in samples from all three shots and facilitated comparison of the resujts from different laboratories. 6. All Sr® and Sr® R-values have been normalized to the LASL values by means of the Koa samples analyzed at both LASL and NRDL. 7. All Y*! R-values have been normalized to the NRDL values by means of the Koa samples analyzed at both LASL and NRDL. 8. The term “probe velocity” refers to the pumping speed in the gaa-particle coincident sampler. Samples collected at a low probe velocity are very likely nonrepresentative of the cloud. 9. On Koa, the massive samples were collected on the 60,000-foot height line; the Wilson special sample was from the general fallout. 10. The fine and coarse fractions for the Koa and Oak size-separated samples were separated at a nominal fall rate of 1 cm/sec. Nominal fall rates for the Walnut fractions were: fine fraction, less than 0.1 cm/sec; medium fraction, 0.1 to 1.0 cm/sec; and coarse fraction, greater than 1 cm/sec. 11. The sampling altitudes given for Aircraft 978 on Walnut and 981 on Oak are thought to be too high, but more reliable figures are not available. 60
