摘　　要：为使工业60Co单板源更好地为核电、航天等部门使用的材料、电子元器件抗辐射性能研究提供辐照技术服务,对本辐射场进行了以10 cm为单位、理想空间中剂量场分布的理论计算和实际分布的实验测量,获得散射吸收因子为0.86,据此建立了经验计算公式,给出了测量数据的不确定度,对实验结果进行了讨论。In order to supply a better irradiation service for materials and electronic devices used in the field of astronavigation and nuclear power plant,the distribution of dose rate was theoretically calculated based on the ideal space model meanwhile the distribution of dose rate was measured with interval of 10 cm.It was found that the scattering absorption factor was determined to be 0.86 compared with calculated results.With the use of the experimental equation established in this paper the uncertainty of measurement was supplied and relative results were discussed.
