A supporting device for radiation protection comprises a like C shape structure and a supporting structure. The like C shape structure includes a horizontal bar and two-side bars. The tow-side bars are located on the two end of the horizontal bar, separated to allow a person to get into the device. Furthermore, we can hang a back lead apron on the tow-side bars to avoid the radiation from the back. The supporting structure includes three bars. One end of the three bars is connected to the horizontal bar or two-side bars separately. The other end of three bars has a wheel to make the whole device moveable easily. When using the supporting device, one can have radiation protection material on the horizontal bar and two-side bars of the C shape structure to keep out the radiation. Furthermore, a back protection can be added by hanging the back protection on the two-side bars.一種輻射防護支撐裝置,包括一類似ㄇ字型結構與一支撐結構,其中ㄇ字型結構包括一水平構件與兩側構件,兩側構件分立於水平構件之兩側,分開大於使用者的肩膀寬度,俾使得使用者操作時進出容易,兩側構件並且往後延伸;支撐結構包括三支撐桿,支撐桿的一端分別結合於ㄇ字型結構的水平構件與兩側構件,支撐桿之另一端則都設有輪子,可使得裝置可移動;使用時,使水平構件不會擋住使用者之視線,且在水平構件與兩側構件上吊掛輻射防護,尤有進者,可在使用者背後在兩側構件上再吊掛一背後輻射防護,以阻隔使用者背後的游離輻射,俾形成較佳的輻射防護效果111‧‧‧水平構件112‧‧‧兩側構件A113‧‧‧兩側構件B211‧‧‧支撐桿A212‧‧‧支撐桿B213‧‧‧支撐桿C214‧‧‧輪子31‧‧‧鉛衣311‧‧‧鉛衣袖口32‧‧‧後鉛衣
