| Abstract:: |
| Objective To estimate physical doses of the six exposed persons in the “4.26” 60 Co radiation source accident of Henan Province. Methods The exposure models of the persons were established by survey and simulation.The distribution of exposure rate in radiation field was measured with LiF(Mg,Cu,P)TLD.The doses of the exposed persons “Mei”(female),“Wang”(8 years old,male) and “Tian” were measured with an anthropomorphic phantom.The doses of “Yong”,“Min”.“Yi” were estimated using the method of tissueair ratio. Results The doses of 19 organs and tissues of “Mei”,and “Wang” were presented in this paper.The average whole body doses of “Mei”,“Wang”and “Tian”are 6.1 Gy,3.4 Gy and 2.4 Gy,respectively.Their weighted stem cell doses are 5.0 Gy,2.6 Gy and 2.3 Gy, respectively.For “Yong”,“Min”and “Yi”,their average whole body doses are 1.1 Gy,0.9 Gy and 0.7 Gy,respectively.Their weighted stem cell doses are 1.1 Gy,0.9 Gy and 0.8 Gy,respectively. Conclusion The physical doses obtained in this work are consistent with the biological doses,clinical laboratory tests and symptoms.Reliable information of dosimetry is provided for the clinical diagnosis and treatment,and doseeffect study. |
