IEC 60601-2-64:2014适用于用于治疗患者的光离子束医用电气设备（以下简称医用电气设备）的基本安全和基本性能。本特殊标准包括型式试验和现场试验，分别适用于在人类医疗实践中用于放射治疗的医用电气设备的制造和某些安装方面，包括可编程电子子系统自动控制操作参数的选择和显示的设备，在正常使用中，发射一束光离子，每个核子的能量在10 MeV/n到500 MeV/n之间。 关键词:核医学，辐射剂量学。

IEC 60601-2-64:2014 applies to the basic safety and essential performance of Light Ion Beam Medical Electrical equipment, hereafter referred to as ME equipment, used for treatment of patients. This particular standard, with the inclusion of type tests and site tests, applies respectively to the manufacture and some installation aspects of ME equipment intended for radiotherapy in human medical practice, including those in which the selection and display of operating parameters can be controlled automatically by programmable electronic subsystems, that, in normal use, deliver a radiation beam of light ions having energy per nucleon in the range 10 MeV/n to 500 MeV/n. Key words: nuclear medicine, radiation dosimetry.
