Factors that may reduce the dose of radiation, from diagnostic and therapeutic x-ray procedures, to the patient and to the occupational and non-occupational worker are outlined. Suitable basic radiation measuring apparatus is described. It is recommended that, in diagnostic radiography, relatively high kilovoltage, proper cones, collimation and adequate filtration be used. Some specific recommendations are made concerning fluoroscopic, photoroentgen and portable x-ray examinations. Film monitoring of personnel is advisable. Examples are given of protective devices to lessen the dosage to the occupational worker. It is the responsibility of the radiologist or physician in charge to ensure that the x-ray equipment is safe to operate and the radiation dose to the patient is kept to a minimum. The roentgen output for all radiographic examinations should be known by the responsible user.
文中概述了一些可减少诊断和治疗性X射线程序对患者、职业和非职业工作人员辐射剂量的因素。介绍了适用的基本辐射测量仪器。建议在诊断性X射线摄影中使用相对较高的千伏、合适的锥形物、准直和充分的过滤。针对荧光透视、光荧光摄影和便携式X射线检查给出了一些具体建议。对工作人员进行胶片监测是可取的。给出了减少职业工作人员剂量的防护装置示例。负责的放射科医生或医师有责任确保X射线设备操作安全，并将患者的辐射剂量保持在最低水平。所有X射线检查的伦琴输出量应由负责的使用者知晓。
