In 100 patients, the X-ray exposure during routine angiocardiography was measured from which calculations were performed for the integral dose (the energy transferred to the body by the exposure), the mean body dose and the radiation risk (according to ICRP 26, 1977). Fluoroscopy contributed 21% and angiocardiography 79% of the total exposure. The mean body dose was 0.9 rd. The average of the area-dose product was 10,200 Rcm2 with a skin exposure in the central beam of 36.1 rd. The genetic risk (probability of X-ray-induced mutation in progeny) is 1 : 75,000 after average exposures and 1 : 7,700 at maximal doses. The somatic risk (probability of X-ray-induced lethal disease) in the patients studied is 1 : 11,000 after average exposures and approximately 1 : 4,400 at maximal doses. The genetic and somatic risks, thus, are small as compared with those of cardiac catheterization and contrast angiocardiography.
对100例患者在常规心血管造影期间的X射线照射量进行了测量，并据此计算了累积剂量（照射传递给身体的能量）、平均人体剂量和辐射风险（根据国际放射防护委员会1977年第26号出版物）。透视占总照射量的21%，心血管造影占79%。平均人体剂量为0.9拉德。面积剂量乘积的平均值为10200伦琴平方厘米，中心射束处皮肤照射量为36.1拉德。平均照射后遗传风险（后代中X射线诱发突变的概率）为1:75000，最大剂量时为1:7700。在所研究的患者中，平均照射后躯体风险（X射线诱发致命疾病的概率）为1:11000，最大剂量时约为1:4400。因此，与心导管检查和造影心血管造影相比，遗传和躯体风险较小。
