Paddy soils were collected nationwide from 12 - 15 sampling sites from 1987 to 2001, and rice plants grown on these soils were also collected. The geometric-mean-TFs of 137Cs were 0.0026 for brown rice and 0.0011 for polished rice, and for 90Sr they were 0.015 and 0.0059, respectively. When the distribution ratios of 137Cs and 90Sr in polished rice to brown rice were calculated, the average ratios were 0.35 for 137Cs and 0.36 for 90Sr, indicating that these radionuclides were mainly associated with the bran. Then the TF of 137Cs was particularly focused on in this study because the number of available data was sufficient for statistical analysis (i.e. the variation in the TFs for Cs from paddy soils to rice grains). The variation of TFs of 137Cs for polished rice at each site year-to-year was very small, being within the range of two orders of magnitude, whereas the variation of 137Cs-TFs for polished rice was somewhat greater between sample sites across Japan. The relationships between TF 137Cs and soil properties (acidity [pH], exchangeable-potassium, cation exchange capacity and clay content) were also investigated. No correlations were found for 137Cs-TFs and these properties which was difficult to explain. More data must be collected for both TF and soil properties.","subitem_description_type":"Abstract"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"548640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"548641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Komamura, Musako"}],"nameIdentifiers":[{"nameIdentifier":"548642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"548643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"548644","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Variation of transfer factors of radionuclides for food crops in Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Variation of transfer factors of radionuclides for food crops in Japan"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-09-14"},"publish_date":"2006-09-14","publish_status":"0","recid":"53756","relation_version_is_last":true,"title":["Variation of transfer factors of radionuclides for food crops in Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:08:58.242886+00:00"}
