Shielding calculation of medical Co-60 brachytherapy room

Objective: Using calculation to evaluate the shielding of construction project work of the Co-60 brachytherapy room in the hospital, prevention and control of radiation hazards to protect the health and safety of radiation workers and the public. Methods: Calculation was done according to the relevant national standards and the basic principles of radiation protection design. Results: The gamma ray was used as an overview of the factors affecting the shielding thickness of the Co-60 brachytherapy room so as to determine the shielding formula. Conclusion: The shielding of radiation protection facilities in Co-60 brachytherapy room construction project basically meets the hygienic requirements of architectural design. (authors)
