<p><P>PROBLEM TO BE SOLVED: To suppress variations in measurement values when starting measurement. <P>SOLUTION: A semiconductor-type radiation detection element (2) is irradiated with high-energy X-rays (41) which pass through the radiation detection element (2). After finishing the irradiation, radiation being a measuring object is measured by the use of the radiation detection element (2). As a result of this, donors and acceptors being in ionic states diminish in portions of an i layer corresponding to the vicinities of electrodes on the incidence side of the radiation and on its opposite side, by the irradiation of the high-energy radiation. Consequently, even if radiation measurement is repeated after that, measurement values do not vary. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
