The present invention relates to syringe loading shields for use with syringes during the drawing of aliquots of radioactive materials from shielded vials containing same. 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 shield having a high density viewing window recessed therein is disclosed which is comprised of a plurality of sheaths. A novel hand shield and syringe for use with radioactive materials are also disclosed.
A syringe shield for use with a syringe at least during the use of that syringe for drawing aliquots of radioactive materials from the mouth of a vial having a vial shield surrounding at least a portion of said mouth;
A syringe shield for use with a syringe at least during the use of that syringe for drawing aliquots of radioactive materials from the mouth of a vial having a vial shield surrounding at least a portion of said mouth;
A hand shield for use with a syringe at least during the use of that syringe for drawing aliquots of radioactive materials from a vial, comprising a shielding disc comprising a plurality of layers of material, at least one of which is a shielding material, said disc having an aperture centrally defined therein for receiving a syringe barrel therethrough.
A radioactive dosage calibration apparatus, comprising:
