  • Device for marking fluent materials
    Patent number: 4010109
    Abstract: The invention is concerned with a device for use in marking fluent materials with a radio-active substance. A radio-active substance in an isotope generator continuously produces a relatively short life radio-active daughter substance and a solvent for the daughter substance is fed continuously in controlled quantities under pressure into the generator to dissolve the daughter substance and form an isotope carrier. The isotope carrier is discharged from the generator through a fixed pipe to an equalizing reservoir from which it is dosed into a container for the fluent material through a control valve.
