90 Sr is a product of nuclear fission. It is present in significant amount in spent nuclear fuel, in radioactive waste from nuclear reactors and in nuclear fallout from nuclear tests.

Strontium-90 is a radioactive isotope that is produced as an artificial product primarily in nuclear fission and occurs in the fallout from nuclear explosions and nuclear accidents. In medicine, Sr-90 is used as a radioactive source for superficial radiation therapy for some types of cancer.

Methods: Two-cycle electrolysis procedure was developed for separation of 90 Y from 90 Sr in nitrate solution. The first electrolysis was performed for 90 min in 90 Sr (NO3)2 feed solution at pH 2-3 at a potential of -2.5 V with 100-200 mA current using platinum electrodes.

This publication presents technologies for the development of 90Sr/90Y and 188W/188Re generator systems and provides details about the analytical methods that are used for evaluating the radionuclides to be used for basic research and radiopharmaceuticals preparation.

May 1, 2008 · Objectives: To develop generators to obtain n.c.a grade 90Y from 90Sr for targeted therapy. Methods: Two systems were developed.

Feb 1, 1978 · A 90 Sr 90 Y MINIGENERATOR has been developed for as an educational aid. It consists of ion exchange paper impregnated with Amberlite IR-120 resin on which 0.1 μCi of 90 Sr is deposited and from which 90 Y is eluted with a dilute solution of disodium ethylenediaminetetraacetic acid (EDTA).

May 1, 2015 · A novel 90 Sr– 90 Y generator system was developed for separation of 90 Y from its long-lived parent, radionuclide 90 Sr based on a hollow fiber supported liquid membrane (SLM) system operated under closed-loop recirculation of both aqueous phases.

Feb 1, 2008 · Two-cycle electrolysis procedure was developed for separation of 90 Y from 90 Sr in nitrate solution. The first electrolysis was performed for 90 min in 90 Sr (NO 3) 2 feed solution at pH 2–3 at a potential of −2.5V with 100–200 mA current using platinum electrodes.
