Application of MlS method in safety risk assessment of waste source control project

Objective: The purpose of this paper is to explore the suitability of the MLS method for safety risk assessment of radioactive source control projects. Methods: Take a case of a radioactive waste control project of cobalt radiation chamber at an agricultural research institute in NingXia, MSL method is used for risk assessment at construction site of the radioactive source control projects. Results: By scoring and calculating the six risk factors: object strikes mechanical injury, heat injury, fire, ionizing radiation damage and leakage of radioactive material, obtain the risk rating of construction site of the radioactive source control projects, give advices to risk control, and applied in the project safety risk prevention. Conclusion: Therefore, this paper concludes that the MLS method is a suitable safety risk assessment method for radioactive source control projects. (authors)
