To estimate the external exposure dose using electron spin resonance technique, we use a "standard sample" which were prepared at each laboratory with each preparation protocol. It is necessary to unite the preparation protocol for the "real" standard sample. In the point of view of the enamel extraction method, no difference was observed for five dose responses between the absorbed dose and the CO radical intensity.
