<p><P>PROBLEM TO BE SOLVED: To provide a simple exposure dose measuring method capable of inexpensively measuring the exposure dose of a wide body part, without mounting a large-scale exposure dose measuring device. <P>SOLUTION: In this method, an exposure dose indicator having a radiation color composition is attached to a patient's skin, an operating gown, a hat for operation, or an exposed body of a sheet for operation, and is exposed, and then the color of the exposure dose indicator is compared with the standard color previously produced by irradiating the radiation dose, corresponding to the exposure dose to a similar kind of the indicator, thereby determining the exposure dose. The radiation color composition is a composition, containing a polymeric compound having at least either of halogen group or acetal group and hydroxyl group, a color electron donor organic compound, an active species product organic compound for coloring the electron donor organic compound in response to the exposure dose, and a radiation-absorbing and/or radiation fluorescent agent, or is a composition containing either polyacethylene compound or diarylethene compound. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
