Integrated protection of radioactive injecting drug and design of protective system

Objective To develop an integrated protection method and protective system for the radioactive injecting drug.Methods The injector tubing with low radiopharmaceutical was prevented from radial ray radiation by an external tunnel protective cover made of tung alloy, which had a injection scale viewing window of transparent lead glass at the axial direction. The radiation protection was realized for the drug with high radioactivity by some protective device during transportation and injection. The two kinds of drugs were distributed into the injector through the loading instrument in the protective cabinet. Results The integrated protective method and device were combined to realize radiation protection during radioactive drug injection. Conclusion The integrated protective method and device can provide protection against radiation during distribution, transportation and injection, and can reduce the radiation dose of the nuclear medicine staff.
