A sterile pyrogen-free generator for ultra-short half-life 81mKr has been developed. During initial loading, the binding efficiency of 81Rb is 90--99%. The count rate during perfusion is 3 x 10(5) counts per minute for a 1,9 GBq (50 mCi) 81Rb generator. The generator has been used for routine and special investigations of lung perfusion and ventilation and for myocardial perfusion during catheterization.
