X-ray equipment, used for radiation therapy at low voltages, is frequently operated in small hospitals which do not have full-time physics staff. Most of the X-ray units involved are not fitted with dose-rate monitors which would allow continuous control dose so that the output must be checked at frequent intervals by the radiographer using a suitable instrument. The design criteria for such an instrument are discussed and its construction described in detail together with the tests and field trials carried out. The instrument is designed to measure dose rates from 2500 rad min-1 at 10 kV to 50 rad min-1 at 250 kV. It has been possible by use of the instrument to determine the 'normal' behaviour of each X-ray unit and to establish criteria by which 'abnormal' behaviour can be determined.
用于低电压放射治疗的X射线设备，常在没有全职物理工作人员的小医院中使用。所涉及的大多数X射线装置未配备剂量率监测器，而剂量率监测器可实现剂量的连续控制，因此放射技师必须使用合适的仪器定期检查输出剂量。本文讨论了这种仪器的设计标准，并详细描述了其构造以及所进行的测试和现场试验。该仪器设计用于测量10 kV时2500 rad min⁻¹至250 kV时50 rad min⁻¹的剂量率。通过使用该仪器，可以确定每个X射线装置的“正常”行为，并建立可用于确定“异常”行为的标准。
