X线片是一种理想的评价血液制品标准照射量的测量手段,用平行对照双视野医学线性加速器辐射血液主要目的是减少输血相关移植物抗宿主病(TA-GVHD)。置血液制品在有机玻璃盒中以29.5-31.7Gy进行照射,适用量决定于环形电离室和X线片,X线片的结果与电离室各部位测得的吸收量有+/-6％误差(95％的可信限)。X线片测量的适用量为30.95+/-2.6Gy,两个标准差以内,同平常的可视照射片一样,X线片也可 X-ray is an ideal measure of the standard exposure of blood products. Radiation of blood with a parallel-control, dual-field medical linear accelerator is primarily aimed at reducing transfusion-associated graft-versus-host disease (TA-GVHD). Blood products in the plexiglass box to 29.5-31.7Gy irradiation, the amount depends on the annular ionization chamber and the X-ray film, the results of the X-ray and the ionization chamber measured in all parts of the absorption of + -6% error (95% confidence limit). X-ray measurement of the amount of 30.95 +/- 2.6Gy, two standard deviations within the same with the usual visual irradiation, the same X-ray film
