[0099] In a specific implementation, in the initial state, when the pneumatic jaw 9 of the main box 1 is closed, the high-energy radiation source 26 is opened, and the main box 1 becomes a closed space. At this time, the sampling pneumatic jaw 8 is opened, and the sample to be tested is placed on the sample holder 17.
