<p>PURPOSE:To improve space resolving power by using a scintillator consisting >=2 kinds of single crystals of cerium-activated gadolinium silicate expressed by Gd2(1-x)Ce2xSiO5 where x is different in a 5X10<-4=x<=10<-2> range. CONSTITUTION:A multi-channel type radiation detector is constituted by using the scintillator consisting of >=2 kinds of the single crystals of the cerium- activated gadolinium silicate expressed by Gd2(1-x)Ce2xSiO5 where x is different in a 5X10<-4=x<=10<-2> range. Since the base body of the scintillator can be constituted of the same crystal in such a manner, the characteristics such as coefft. of radiation absorption can be equalized and the space resolving power is improved.</p> |
