0018933 eee DELETED 6. All Sr8? and sr?9 R values have been normalized to the LASL values by means of the KOA samples analyzed at both LASL and NRDL. 7. All x?! 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 gas_o particle coincident sampler. Samples collected at a low probe velocity : may be suspected of being biased with respect to particle size. 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 fractions for the KOA and OAK size-separated samples were expected to contain a large proportion of particles having fall rates less than 1 cm,/sec. Nominal falling rates for the WALNUT fractions were: fine fraction, less than 0.1 cm./sec.; medium fraction, 0.1 - 1.0 cm./sec.; 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.
