PURPOSE:To obtain the element material which is stable in the stability of radicals and can detect a radiation dose with high sensitivity by using trapidil and/or glycyrrhizine or a mixture composed of the trapidil and/or glycyrrhizine and CaCO3. CONSTITUTION:The construction of the dosimeter element consists of the element material 1, a plastic holder 2, a plastic retainer 3, and a pin 4 for mounting to clothing. The trapidil and/or glycyrrhizine or the mixture composed of the trapidil and/or the glycyrrhizine and CaCO3 is used as the element material 1. The powder itself may be used as it is for the element material or may be molded to compressed pellets, etc. This element material is extremely narrow in the line width of the electron spin resonance (ESR) signal of the radicals generated by the irradiation of radiations and has the excellent stability of the radicals.
