FIELD: medical equipment.
SUBSTANCE: invention refers to an infusion system. System comprises strontium-rubidium generator of radioactive isotopes, producing radioactive eluate by elution, beta-radiation detector, gamma radiation detector and controller. Beta-radiation detector and the gamma radiation detector are installed for measurement of beta radiation and gamma-radiation emitted by the radioactive eluate, respectively. Controller can be configured to determine rubidium activity in the radioactive eluate based on the beta radiation measured by the beta detector, and determining activity of strontium in the radioactive eluate, based on gamma-radiation measured by the gamma-ray detector.
EFFECT: technical result is exclusion of long-living radioactive isotopes contaminating eluate to patient.
