Abstract:
1. A holder device for analyzing characteristics of a dosimeter, in which the dosimeter is located in a desired direction on a radiation path along which radiation is irradiated from a radiation emitter, and a radiation absorbance characteristic is recognized according to a radiation dose absorbed by the dosimeter, comprising: a lower plate having a specific thickness and placed on a supporting surface facing the radiation emitter; an upper plate laminated on the upper surface of the lower plate and allowing the dosimeter to be fixedly located between the lower plate and the upper plate; and one or more height control plates disposed between the lower plate and the supporting plate so as to control the distance of the dosimeter with respect to the radiation emitter, wherein the dosimeter is a metal oxide semiconductor field effect transistor (MOSFET) dosimeter, the lower plate includes a plurality of grooves extending in parallel from one fringe of the lower plate towards the center portion thereof and containing the MOSFET dosimeter therein, and the lower surface of the upper plate is provided with a groove having space for containing the MOSFET dosimeter in addition to the grooves of the lower plate.
