Evaluation on the Radiation Protection at Preparing and Injecting ~(18)F-FDG

To monitor the γ-ray radiation dose level in different sites at preparing and injecting ~(18)F-FDG, the radiation dose level of γ-ray in cycltron room and surrounding areas, synthesis room, injection room, scanning room are tested. The results show that the γ-ray radiation dose in different sites varies largely, the γ-ray shielding equipment of underground is up the grade, although there is the protected shielding in injection room, but the radiation dose level is still high. To the operator, the shielding protected efficiency is less than the cyclotron room and synthesis room, the γ-ray radiation dose level surroundings the patients who have been injected radioactive isotope is also high, these sites are main points of the protection.
