Abstract Objective To evaluate the radiation effects to the surrounding environment and the radiation workers and the public in the micro PET Center. Methods By the surrounding pathway radiation level the on-sitemonitoring centers the main radioactive sources of pollution and contamination pathway were analyzed. Results In the operational process of the micro-PET center, the radiation dose to the radiation workers and the public is 0.31 mSv/a and 0.1 mSv/a, causing some radiation to the surrounding environment. Conclusion The impact of the micro-PET project on the environment、the public、the radiation workers is in comformity with the relevant provisions. The radioactive waste by effective treatment can meet the requirements standards to discharge.
