文摘

The developed process for producing 90Y is based on semicountercurrent extraction separation with phase inversion on two series-connected blocks of centrifugal extractors. The main advantage of the suggested process over the known procedures is the practically unlimited output capacity of the installation: from trace amounts to several tens of curie in cycle; the possible limitations are only imposed by the chemical or radiation resistance of the materials and chemicals used. Production of 90Y takes from 30 to 60 min. The warranted degree of 90Y separation from the parent 90Sr (with respect to activity) is 10-9% by the day of calibration.
