摘要：
The interlaboratory comparison that 148 laboratories participated was performed to understand the validity and variability of measurements with NaI(Tl) scintillation detectors for samples near the standard limit for radioactive cesium in general foods in Japan. Brown rice grains with certified massic activity of radioactive cesium were used as test samples. The medians of the reported massic activities of radioactive cesium,Cs-134, and(137)Cs in brown rice grains agreed with the reference values. On the point of view for inspection, more than 92% of the reported values were within the acceptable range.
