内容記述 | The authors measured concentration of ^<131>I, ^<134>Cs and ^<137>Cs in agricultural soil (0-15cm) which were sampled in Miyagi, Ibaraki, Tochigi, Gunma, Saitama, Chiba and Kanagawa Prefecture on the basis of the request of the Ministry of Agriculture, Forestry and Fisheries (MAFF) and the prefectural governments just after accident of the Fukushima Daiichi Nuclear Power Plant (FDNPP) from March 25 to April 2, 2011. Fukushima Prefecture, where the FDNPP is located, and northern Ibaraki Prefecture were not included. This paper shows the data of ^<134>Cs and ^<137>Cs including ^<131>I which are unpublished. The ranges of ^<131>I, ^<134>Cs, ^<137>Cs, radioactive Cs (^<134>Cs+^<137>Cs) are from 18.1 to 2600 Bq kg^<-1> , from 5.8 to 1980 Bq kg^<-1>, from 7.0 to 2060 Bq kg^<-1>, from 12.8 to 4040 Bq kg^<-1> , respectively. In general the concentrations are high in southern Miyagi, middle Ibaraki and northern Tochigi Prefecture where are near to the FDNPP. The range of ^<131>I / ^<137>Cs concentration ratio shows the large difference from 0.76 to 11.9. The averages of the ratio in each prefectures are 3.71 in Miyagi Prefecture, 6.10 in Ibaraki Prefecture, 2.94 in Tochigi Prefecture, 2.11 in Gunma Prefecture, 3.28 in Saitama Prefecture, 4.03 in Chiba Prefecture and 3.50 Kanagawa Prefecture. This results shows the ^<131>I / ^<137>Cs ratio at the areas is deferent with the time of passing of radioactive plume and the weather at deposition. The average ^<134>Cs/^<137>Cs ratio as 0.92 in Tochigi Prefecture is lower than the value as 0.96 and 0.97 in Ibaraki and Tochigi Prefecture respectively. However it is difficult to conclude that there is difference ^<134>Cs/^<137>Cs ratio between the prefectures in low radioactive Cs concentration. | |||||||||||
