A COMBINED OPTIMIZATION METHOD FOR RADIATION SHIELDING DESIGN IN MIXED RADIATION FIELD MEASUREMENTS

Xiong Hua~1 Fan Ruyu~2 Kang Kejun~1(1.Dept.of Engineering Physics Tsinghua University,Beijing,100084;2.Northwest Inst.of Nucl.Tech,Xi'an,710024)  
One single shield design was not suitable for all measuring points with different local radiation characters and measurement objects in mixed-radiation field.A new method is needed for quantitative evaluation and automatically optimizing design of radiation shielding to adapt it to various conditions.Based on cost-benefit principle,we propose an evaluation method for radiation shielding,and implement a combined optimization method based on genetic algorithm.Experiments show that the evaluation method is consistent with results given by various references and MCNP;in typical condition,influence of noise radiation from optimized design is 44 % of the traditional design.The combined optimization method is able to automatically optimize design with certain radiation characters and measuring point parameters,that is useful for project design and data analysis.
