摘　　要：用３名供血者的外周血样，作６０Ｃｏγ－射线辐照，辐照剂量点为０、０．０６５、０．１２０、０．２６０、０．４６０、０．６３０Ｇｙ，其分析１３３８２个中期细胞的染色体畸变，建立辐射剂量一效应曲线。结果表明“双”和“双＋环”畸变适合非线性数学模型。dose-effect curve obtained by analysis of chromosome aberrations after irradiation of pe-ripheral blood samples from three donor,at 6 different doses(0,0. 065,0.120,0.260,0.460,0. 630Gy)of 60Co γ-rays is presented.For the elaboration of this curve,13382 cells have beenanalyzed.Dicentrics and dicentrics+rings aberration fit very well to the no-linearqtiadratic mod-el.
