摘要

用外周血淋巴细胞染色体畸变（双十环）和微核的剂量效应曲线估算了5例受,60,Co γ线事故照射病人的生物剂量。结果表明，在照后早期，用上述两种方法估算的剂量与物理剂量基本一致。尤其对较均匀照射的3例（A、B和E）“双十环”剂量与物理剂量相当吻合，同时发现，用微核率估算的剂量偏高。本文对上述结果进行了讨论。

Abstract

Biological doses of 5 cases exposed to ,60,Co γ-ray were estimated by the curves of relationships between radiation dose and chromosome aberations and micronuclei of peripheral blood lymphocytes. The results indicated that biological dose estimated by "die.+ r." and micronuclei were quite approximate to the physical dose at early phase of post irradiation. Specially, in 3 cases of uniform doses, the doses estimated by "dic.+ r." were nearly identical to the physical dose. At the same time, it was showed that dose estimated by micronuclei were higher than those of "dic.+ r." doses.
