Claims
- 1. A method of injecting a radioactive substance into a well, comprising the steps of:
- transferring the radioactive substance into a first cavity of a single radioactivity shielding container;
- transferring a diluting substance into a second cavity of the container;
- moving the container to the well;
- flowing the radioactive substance from the first cavity;
- flowing the diluting substance from the second cavity into the flowing radioactive substance for mixing therewith;
- flowing at least a portion of the mixed radioactive substance and diluting substance into the well; and
- flowing any remaining portion of the mixed radioactive substance and diluting substance into the second cavity of the container.
- 2. A method as defined in claim 1, wherein the step of flowing at least a portion of the mixed substances into the well includes:
- pumping a fracturing fluid into a fluid coupling attached to the wellhead of the well; and
- pumping the mixed radioactive substance and diluting substance into the fluid coupling.
- 3. A method as defined in claim 1, wherein:
- the step of flowing the radioactive substance from the first cavity includes:
- connecting the first cavity in fluid communication with an inlet of a metering pump; and
- actuating the metering pump; and
- the step of flowing the diluting substance from the second cavity into the flowing radioactive substance for mixing therewith includes:
- connecting an outlet of the metering pump in fluid communication with a first inlet of a pressurizing pump;
- connecting the second cavity in fluid communication with a second inlet of the pressurizing pump; and
- actuating the pressurizing pump.
- 4. A method as defined in claim 3, wherein the step of flowing at least a portion of the mixed substances into the well includes connecting an outlet of the pressurizing pump in direct communication with the mouth of the well.
