Radiation environment monitoring and evaluation of an application of ³²P in a university

Objective: To evaluate the radiation impact on surrounding environment from the application of ³²P in a university. Methods: According to the relevant national standards, the monitoring methods were used, and the limits were taken as evaluation criteria. Results: The air kerma rate in the operating room ranged from 62.8 n Gy/h to 108 n Gy/h, it was within the natural background level of the city. The β surface contamination in the control area was 0.057 ∼ 0.235 Bq/cm², it also conformed to the Basic Standards for Ionizing Radiation Protection and Radiation Source Safety (GB 18871-2002). The total alpha and beta activities in the waste water were 0.039 Bq/L and 9.37 Bq/L, also below the their corresponding limits of 1 Bq/L and 10 Bq/L, respectively. Conclusion: The application of ³²P in the university project is safe for professional staff and the general public with less impact on the environment. (authors)
