4. Corrects the total count for the wire for the small amount of
radioactive decay that occurred in the few minutes between the sample
count and the standard count.
5. Computes the ratio: [total count for sample/total count for
standard (corrected)]
6. Repeats all the above for the 0.511-MeV gamma ray for copper-64 and
(in the longer counts) for the 0.658-MeV gamma ray for silver-110.
7. Computes the ratios: [sample to standard (for copper)/sample to
standard (for gold)] and [sample to standard (for silver)/sample to
standard (for gold)].
