DATA RELIABILITY
3.2.1
Cross-Contamination of Koa Samples.
As discussed in Section 2.3.2,
a preliminary examination of the samples from Shot Koa, shortly after their receipt.
at LASL, indicated that they might be badly contaminated with debris from Fir.
If
this were the case, the fission ratios from the Koa cloud data could not be used
for the determination of fallout partition since they would not be representative
To investigate the extent of cross-contamination, the Koa

Eence the quantities of Mo and Kr introcuce
into the Koa cloud from Fir were small enough so that they would have a negligible
effect on the fission ratios.
