 note = {Strontium 90 activity concentration was measured in four soil samples (0-10 cm) collected from the exclusion zone around the Fukushima Daiichi Nuclear Power Plant (FDNPP). The open chemical digestion method was used for sample decomposition with a mixture of acids. The strontium separation was achieved with strontium selective resin (Sr-resin). The activity of strontium 90 was determined with liquid scintillation counter (LSC). Owing to the atmospheric nuclear weapon tests, the soil in Japan is contaminated with strontium 90. Related to this background level, significant Fukushima contamination was not noticed by the results of this study. The detected strontium 90 activities were 8.9±0.8, 20±1.3, <6.8, and 23.4±1.5 Bq kg-1, respectively.},
