Description

>The materials and methods used for the long-term nuclide pairs are essentially the same as those previously described. (April - June Report). The split planchet method was used to determine the resolving time of the tracerlab superscalar counting apparatus which is currently in use. A planchet was split in two and a sample of nuclide placed in each half and counted. From these results a formula for calculating true counting rates was evolved. Data on resolving time loss for the Superscalar are tabulated. Transmission values of Sr/ sup 89/- Ct/sup 14/ mixture were measured to determine the degree to which ... continued below

Description

>The materials and methods used for the long-term nuclide pairs are essentially the same as those previously described. (April - June Report). The split planchet method was used to determine the resolving time of the tracerlab superscalar counting apparatus which is currently in use. A planchet was split in two and a sample of nuclide placed in each half and counted. From these results a formula for calculating true counting rates was evolved. Data on resolving time loss for the Superscalar are tabulated. Transmission values of Sr/ sup 89/- Ct/sup 14/ mixture were measured to determine the degree to which error in these values can be reduced by long counting periods. Data on P/sup 32/ and C/ sup 14/ tagged rubber age counts are tabulated. Also, rubber samples were prepared by adding Ca/sup 45/, Cl/sup 36/, Nb/sup 95/, and T c/sup 99/, mixing and vulcanizing and isotope pairs (Ca/sup 45/- Cl/sup 36/ and Nb/sup 99/-Tc/sup 99/) were similarly incorporated in other samples. Ground and suspended samples of these preparations were age counted. The results obtained by incorporating radioisotopes into rubber can not show close correlation between observed and calculated time. Probable reasons for errors and inconsistencies are discussed along with plans for future work. (J.R.D.)
