ABSTRACT
Quality control of 188W/188Re generators from two different manufacturers and two levels of activity each, was carried out.Elution yields, chemical as well as radionuclidic and radiochemical purities, elution profiles along six months, were evaluated.Broad elution profile, high efficiency, with tandem alumina column added, ionic exchange column needed for increase of radionuclidic concentration were characteristics of type I generators.Easy handling with slightly lower yields and high concentrations of activity were observed in type II generators. Similar radionuclidic impurities namely 192Ir, 191Os, 188W, 110mAg, 54Mn, 134Cs and 60Co as well as similar radiochemical yields obtained in the labelling of 188 Re-HEDP were observed with eluates of both generator types.Absorbed doses to radiopharmacy staff were less important in type II generators.
