PATIENT RELATED ISSUES

Every dose administered to a patient must be assayed in a properly functioning radioisotope dose calibrator.

This device must be capable of reliably calibrating doses as small as 10 μCi and well as on the multi-Ci range. Central Radiopharmacies routinely handle activities in the range of 5-15 Ci of Tc99m.

According to current NRC Regulations, administered doses must be within ±20% of the prescribed dose.

Some Agreement States require that administered doses must be within ±10% of the prescribed dose. It is the obligation of the person calibrating the dose, typically the Nuclear Medicine Technologist, to assay the dose and to insure that it meets the specification set down in the 20% rule. The prescribed dose may be modified only by a physician and a note must be made on the requisition and initialed by the physician indicating the change in prescribed dose.
