To solve this problem, we developed a low-energy X-ray camera that detects the characteristic X-ray photons (32~37 keV) that are emitted from Cs-137 to obtain high resolution images. We used a 45- x 45- x 1-mm-thick NaI(Tl) scintillator that was encapsulated in 0.1-mm-thick aluminum and optically coupled to a 2-inch square, position sensitive photomultiplier tube (Hamamatsu Photonics, PSPMT:H12700 MOD) as a imaging detector. The imaging detector was encased in a 2-cm-thick tungsten alloy container and a pinhole collimator was attached to its camera head. The spatial resolution and sensitivity were ~5-mm FWHM and ~0.6 cps/MBq for the 1.5-mm pinhole collimator 10 cm from the collimator surface, respectively. We administered 5MBq of Cs-137 to a soybean seedling, imaged the distribution of radionuclides for six hours, and successfully obtained a high resolution image of it with our developed X-ray camera. We believe our camera will be a powerful tool for such Cs-137 imaging in plants.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor and Francis"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1080/00223131.2017.1323690","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.tandfonline.com/doi/full/10.1080/00223131.2017.1323690"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.tandfonline.com/doi/full/10.1080/00223131.2017.1323690","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-3131","subitem_source_identifier_type":"ISSN"}]},"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":"安藤, 昂輝（名古屋大学）"}],"nameIdentifiers":[{"nameIdentifier":"485052","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本, 誠一（名古屋大学）"}],"nameIdentifiers":[{"nameIdentifier":"485053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"栗田, 圭輔"}],"nameIdentifiers":[{"nameIdentifier":"485054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴井, 伸郎"}],"nameIdentifiers":[{"nameIdentifier":"485055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"尹, 永根"}],"nameIdentifiers":[{"nameIdentifier":"485056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井, 里美"}],"nameIdentifiers":[{"nameIdentifier":"485057","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河地, 有木"}],"nameIdentifiers":[{"nameIdentifier":"485058","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"栗田 圭輔","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485059","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴井 伸郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485060","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"尹 永根","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485061","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井 里美","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485062","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河地 有木","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485063","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Development of a low-energy high resolution X-ray camera for high-energy gamma photon background environments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a low-energy high resolution X-ray camera for high-energy gamma photon background environments"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-03"},"publish_date":"2017-08-03","publish_status":"0","recid":"48261","relation_version_is_last":true,"title":["Development of a low-energy high resolution X-ray camera for high-energy gamma photon background environments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:30:08.001003+00:00"}
