Patent ID: 8852071

Claim:
A device for dispensing a radioactive liquid to a destination, the device comprising: a first valve means; a fluid delivery path for fluid flow from the first valve means to the destination; a metering section connected to the fluid delivery path; and an activity metering unit operable to determine an activity concentration in a radioactive liquid source in system internal units, wherein the activity metering unit determines a level of radioactivity within the metering section of the fluid delivery path as a radioactive liquid is moved into the metering section, wherein a volume for a total activity amount is determined based on the activity concentration in the radioactive liquid source in system internal units, wherein the first valve means is adapted for selectively connecting the radioactive liquid source and a flushing liquid source to the fluid delivery path upstream of the metering section and is adjusted to deliver the total activity amount, wherein the metering section is capable of holding at least two separate amounts of the radioactive liquid having a total volume containing at least one total activity amount of the radioactive liquid from the radioactive liquid source.
