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. aa ” 30 snail shaial bia thease) SECRET - RESTRICTED DATA
