射線裝置分類辦法

2012/1/27 10:08:30

根據(jù)《放射性同位素與射線裝置安全和防護條例》(國務院令第449號)規(guī)定,制定本射線裝置分類辦法。

一、射線裝置分類原則

根據(jù)射線裝置對人體健康和環(huán)境可能造成危害的程度,從高到低將射線裝置分為類、類、類。按照使用用途分醫(yī)用射線裝置和非醫(yī)用射線裝置。

(一)類為高危險射線裝置,事故時可以使短時間受照射人員產(chǎn)生嚴重放射損傷,甚至死亡,或?qū)Νh(huán)境造成嚴重影響;

(二)類為中危險射線裝置,事故時可以使受照人員產(chǎn)生較嚴重放射損傷,大劑量照射甚至導致死亡;

(三)類為低危險射線裝置,事故時一般不會造成受照人員的放射損傷。

二、射線裝置分類表

常用的射線裝置按下列表進行分類。
