4名^（60）Co源辐照事故中受照者的剂量估算

DOSE ESTIMATION OF FOUR VICTIMS EXPOSED TO A SOURCE OF ￣(60)Co IN A ACCIDENT

对一起￣（６０）Ｃｏ源辐照事故中受到过量照射的人员，通过现场调查和模拟试验，确定了照射的几何条件和受照时间，估算了４名受照者的造血干细胞活存计权等效剂量。最后将物理方法与生物学方法估算的剂量数据作了比较。

For 4 victims exposed exceedingly to a source of ￣60Co in a accident ,exposuredgeometrics and time were determined through field investigation and imitating test,and theequivalent whole body dose weighted by hematological stem cell survival were estimated andcompared with the results obtaind using biologic methods.
