目前,我国提倡一对夫妇生育一个子女,要求做到“优生”。为了保障儿童健康成长,本文对25例胎龄8～10个月时在胎内受到诊断X线照射的儿童进行了受照剂量估算和早期生物效应的观察。我们用国产BeO(Na)热释光剂量元件测定孕妇骨盆X线测量时局部皮肤射入量,按胎儿在子宫内的位置,根据空气组织比值,换算出胎儿的受照剂量为2.654～
At present, China advocates a couple to have one child and requires “eugenics.” In order to protect the healthy growth of children, this article 25 cases of gestational age 8 to 10 months in the fetus undergoing diagnostic X-ray irradiation dose estimation and early biological effects were observed. We use the domestic BeO (Na) thermoluminescence dose component measurement of pelvic X-ray measurement of pregnant women when the amount of local skin injection, according to the position of the fetus in the womb, according to the ratio of air tissue, converted fetus dose of 2.654 ~
