Times Cited Count:0 Percentile:0.01(Environmental Sciences)Interlaboratory comparison studies are important for radiation dosimetry in order to demonstrate how the technique is universally available. The set of standard samples are examined in each participating laboratory in the present study. After a set of standard samples together with the samples with unknown doses, which were prepared in the same laboratory as the standard samples, are measured at a participating laboratory, those samples are sent to another participating laboratory for next measurement. There is some small difference observed in the sensitivity (the slope of the dose response line) of the standard samples while the differences in the obtained doses for the samples with unknown doses are rather systematic, implying that the difference is mostly due to the samples but not to measurements.

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.
