R-value is obtained by dividing the observed counting rate ratio of two
nuclides at zero time by the corresponding ratio for a standard fission
sample counted under the same conditions. Table 4.4 lists the weizht,
total activity, and gross decay exponents of one size fraction.
The samples contained less than 1 per cent Cl™. It was rdalized
late in the operation that chloride was lost from the samples by heating
with nitric acid.
However the same result was obtained when the analysis
was run on a portion of 1 size fraction dissolved at room temperature
unier non-oxidizing conditions,
0.075 per cent.
Analyses for Fet* indieated less than
Quantitative analyses for Cat+ were used in conjune-
tion with the total sample weights to calculate the Ca(OH)2 cont=nt
of the size-graded samples, The results are given in Table 4,5. The
two particle sizes having the highest Ca(OH)2 content are the same
sizes thich cannot be obtained in significant quantity by grinding
coral in a mortar. No Fe59 was detected wit? the gamma-ray spectrometer.
