Among the released radionuclides, the behaviour of Cs-137 has been concerned because this radionuclide has a 30-years half-life and a significant amount of Cs-137(1.5x1016 Bq) was released into the atmosphere.  Accordingly, sludge generated in the drinking water plants was also contaminated with the Cs-137 in a certain areas.  Before the accident, the sludge was effectively reused as materials for construction, playground soils, and potting mixes.  Various vegetables are planted in potting mixes in home gardens, and thus the contaminated sludge would be a source of Cs-137 in vegetables.  Intake of the Cs-137-contaminated vegetables causes internal radiation exposure.\nThe standard limit for radiocesium in general foods (100 Bq/kg) has been applied to agricultural crops from April 1, 2012 to ensure safety.  However measurement of Cs-137 in the vegetables harvested in home gardens has not been carried out before their consumption in many cases.  To ensure safety and security, it is important to understand the transfer of Cs-137 from the sludge to vegetables.\nWe recently demonstrated the root uptake of Cs-137 from the potting mix containing the contaminated sludge by Brassica rapa var. perviridis (Japanese name: komatsuna) (Ishii et al. 2013a) and Brassica oleracea spp. (Japanese name: mini cabbage) (Ishii et al. 2013b).  In those experiments, various particle sizes of the sludge were used although particle size is likely to affect soil-to-plant transfer factor (IAEA 2006).  Here, we show the effect of sludge particle size on the uptake of Cs-137 by a leaf vegetable, komatsuna.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"第9回 IWA国際シンポジウム:農産業における廃棄物管理問題-AGRO2014","subitem_description_type":"Other"}]},"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":"石井, 伸昌"}],"nameIdentifiers":[{"nameIdentifier":"703728","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"703729","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"703730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井 伸昌","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703731","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703732","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"703733","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 object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"第9回 IWA国際シンポジウム:農産業における廃棄物管理問題-AGRO2014に参加し、『コマツナによるCs-137の経根吸収に対する浄水発生土の粒子サイズの効果』についてポスター発表を行う。","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"第9回 IWA国際シンポジウム:農産業における廃棄物管理問題-AGRO2014に参加し、『コマツナによるCs-137の経根吸収に対する浄水発生土の粒子サイズの効果』についてポスター発表を行う。"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-02"},"publish_date":"2014-12-02","publish_status":"0","recid":"71557","relation_version_is_last":true,"title":["第9回 IWA国際シンポジウム:農産業における廃棄物管理問題-AGRO2014に参加し、『コマツナによるCs-137の経根吸収に対する浄水発生土の粒子サイズの効果』についてポスター発表を行う。"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:49:54.103067+00:00"}
