Title: RADIATION LEAD FILTER, METHOD FOR EVALUATING PERFORMANCE OF RADIATION DETECTOR, AND RADIATION DETECTOR
Abstract:
A radiation lead filter for limiting the types of radiations when the radiations are detected by using a radiation source from which plural types of radiations are emitted is provided with an identification lead plate layer for identifying particles by making the distances passed by the radiations different, which is disposed between the radiation source and a radiation detector. Thus, a radiation to be measured can be selected, and the performance of the radiation detector can be evaluated with high precision.
