Radiochemical purity of /sup 99m/Tc-pertechnetate
The radiochemical purity of /sup 99m/Tc-pentechnetate obtained from an automated methyl-ethyl-ketone extraction system is compared with that obtained from a commercial generator. The parent /sup 99/Mo used in both systems was produced by neutron irradiation of /sup 98/Mo. The principal contamination in the product from the extraction system is shown to be /sup 186/Re. A study of the amount of /sup 186/Re in successive extractions shows that whereas submicrocurie amounts are present in the Initial extraction, the amount of contamination drops rapidly to zero after the third extraction, In a similar study of the commercial generator, the principal contaminant is shown to be /sup 134/Cs. The amount of this /sup 134/Cs contamination is shown to increase with each elution of the generator. (auth)
