<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-resolution radiation detection element with crosstalk suppressed without damaging scintillators. <P>SOLUTION: The method is one for manufacturing a radiation detection element including; a plurality of mutually separated first columnar scintillators; second columnar scintillators arranged between the respective first columnar scintillators and separated from the first columnar scintillators; and a plurality of light detection members positioned by superimposition on the first columnar scintillators. The method includes the steps of: preparing a substrate having a plurality of flat parts which are surrounded by irregularity parts and mutually separated; and forming the first columnar scintillators and the second columnar scintillators respectively on the flat parts and protrusions. Depth h of a recesses in an irregularity structure and distance d between protrusions satisfy a relational expression of h/d≤1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
