Table 4.4 lists the weight, total activity, and gross decay exponents of one size fraction. The ssmples contained less than 1 per cent Cl~. It was realized 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 siza fraction dissolved at room temperature unier non-oxidizing conditions, 0.975 per cent. Analyses for Fet indteated less than Cuantitative analyses for Cat+ were used in conjunce tion with the total samole weights to calculate the Ca(OH)2 cont=nt of the size-graded samples. The results ars given in Table 4.5. The two particle sizes having the highest Ca(OH)2 content are the same sizes “hich cannot be obtained in significant quantity by grinding coral in a mortar, No Feo? was detected wit> the gamma-ray snectromrater, . 30 sd dats lan SECRET — RESTRICTED DATA
