title: A 81Rb/81mKr generator made by ion implantation.
abstract: Isotopically pure 81Rb was implanted in plastic foils, and the daughter 81mKr was eluted quantitatively by air or by a 0.9% NaCl solution. The elution yield, the purity of the 81mKr, and the washing-out losses of 81Rb were studied as functions of the implantation density. It was seen that the densities below 5 x 10(12) Rb atoms/cm2 provide a high yield for elution both by liquid and air. The first 100 MBq implantation-type generator was tested by making a lung-ventilation study in man.
