RADIATION DOSE MEASURING METHOD AND RADIOLOGICAL IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new radiation does measuring method, radiological image forming method and an ultraviolet ray quantity measuring method.;SOLUTION: In this radiation dose measuring method, radiation which is a measuring object is irradiated to a radiation dose measuring equipment including a terbium and samarium co-activated alkaline earth metal rare earth oxide phosphor comprising a component expressed by a partial composition formula: MIIMIII2:xTb, ySm [Where, MII is one or more kinds of alkaline earth metal selected from a group comprising Mg, Ca, Sr and Ba, MIII is one or more kinds of rare earth elements selected from a group comprising Y, La, Gd and Lu, and x and y are numerical values in the range of 0x≤0.1 and 0y≤0.1 respectively.] and an oxygen molecule, and intercity change per unit hours of green emission emitted from phosphor is measured.;COPYRIGHT: (C)2001,JPO
