ABSTRACT:
The present invention relates to syringe loading shields for use with syringes during the drawing, calibration and injection of aliquots of radioactive materials. Each syringe loading shield is provided with means for shielding radiation emanating from the mouth of the vial during the material-withdrawal, syringe loading process. In a preferred embodiment, the syringe loading shield comprises a radiation detector for detecting and calibrating the radioactive dosage of the material which is drawn into the syringe barrel. In the preferred embodiment, a substantially tubular syringe shield coupleable to a mouth shield-detector assembly is disclosed which facilitates the drawing, calibration and injection of radioactive materials without exposing the radio-pharmacists to unshielded materials.
