              449 号)规定,制定本射线装置分类办法。 In accordance with the "Regulations on the Safety and Protection of Radioisotopes and Ray Devices" (Order No. 449 of the State Council ), the classification method for this radiation device is formulated.

              First, the classification principle of radiation devices

              类、 类、 类。 According to the degree to which the radiation device may cause harm to human health and the environment, the radiation device is classified into Class I, Class II, and Class III from high to low . According to the purpose of use, medical radiation devices and non-medical radiation devices are divided.

              类为高危险射线装置,事故时可以使短时间受照射人员产生严重放射损伤,甚至死亡 , 或对环境造成严重影响; (1) Type is a high-danger radiation device, which can cause severe radiation damage or even death in a short period of time during an accident , or cause serious impact on the environment;

              类为中危险射线装置,事故时可以使受照人员产生较严重放射损伤,大剂量照射甚至导致死亡; (2) Class is a medium-danger ray device, which can cause severe radiation damage to the exposed person in an accident, and large doses of radiation may even cause death;

              类为低危险射线装置,事故时一般不会造成受照人员的放射损伤。 (3) Category III is a low-danger ray device, which generally does not cause radiation damage to the exposed person in an accident.
