摘　　要：本文报道20例尿结石患者体外震波碎石(ESWL)术治疗时所受辐射剂量及治疗前后染色体畸变分析。患者体表皮肤总剂量平均为4.51×10^(-3)C/kg,和大多数医学X线检查相似,因而是可以接受的。但从辐射遗传学角度分析,尽可能减少辐射剂量仍是值得重视的一个问题。结石的性质、医生的经验能影响辐射水平。The radiation dose and the chromosomal aberrations of peripherallymphocytes were studied in 20 patients during ESWL. The dose was measured withcalibrated thermoluminescent dosimeters. Primary results showed an average skin expo-sure 4.50×10^(-3)C/kg per case. The dose level is smilar to that of the patients under-going routine fluoroscopic examination. Therefore, the radiation exposure with patientsfrom the ESWL procedure should be considered acceptable. As chromosome change, toreduce the radiation dose is important for the radiation cytogentics. The factors influe-ncing exposure levels include stone characteristies and physician experience.
