It has been important to evaluate a radiation dose for workers in emergency response at a nuclear accident. In this study, a new device which can evaluate both of external and internal exposure doses was developed and the performance of various environmental radiation monitors including commercially available monitors were tested and compared from the viewpoint of an environmental monitoring at emergency situation. Background counts of the monitors and the ambient dose equivalent rate were measured in Fukushima Prefecture. The detection limit for beta particles was evaluated by the method of ISO11929. The sensitivity for gamma-rays of the dust monitor using a ZnS(Ag) and a plastic scintillator was high, but that of the external exposure monitor using a silicon photodiode with CsI(Tl) crystal was relatively low. The detection limit ranged 190–280 Bq m−3 at 100 μSv h−1, exceeding the detection limit of 100 Bq m−3 in the minimum requirement by the National Regulation Authority in Japan. Use of the shielding with lead is necessary to achieve the minimum requirement. These results indicate that the dust monitor using a ZnS(Ag) scintillator and a plastic scintillator is suitable for the external exposure monitor and the developed internal exposure monitor is for the internal exposure monitor at emergency situation among the evaluated monitors. In the future study, the counting efficiency, the relative uncertainty and the performance of the detection for alpha particles will be evaluated, and it will be considered which type of a monitor is suitable after taking the portability into account.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford University Press"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1093/rpd/ncz104","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1093/rpd/ncz104","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0144-8420","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":"Tamakuma, Y."}],"nameIdentifiers":[{"nameIdentifier":"898615","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamada, R."}],"nameIdentifiers":[{"nameIdentifier":"898616","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, T."}],"nameIdentifiers":[{"nameIdentifier":"898617","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kuroki, T."}],"nameIdentifiers":[{"nameIdentifier":"898618","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saga, R."}],"nameIdentifiers":[{"nameIdentifier":"898619","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, H."}],"nameIdentifiers":[{"nameIdentifier":"898620","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sasaki, H."}],"nameIdentifiers":[{"nameIdentifier":"898621","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwaoka, K."}],"nameIdentifiers":[{"nameIdentifier":"898622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hosoda, M."}],"nameIdentifiers":[{"nameIdentifier":"898623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tokonami, S."}],"nameIdentifiers":[{"nameIdentifier":"898624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwaoka, Kazuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"898625","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":"COMPARATIVE STUDY ON PERFORMANCE OF VARIOUS ENVIRONMENTAL RADIATION MONITORS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"COMPARATIVE STUDY ON PERFORMANCE OF VARIOUS ENVIRONMENTAL RADIATION MONITORS"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-05"},"publish_date":"2019-07-05","publish_status":"0","recid":"76210","relation_version_is_last":true,"title":["COMPARATIVE STUDY ON PERFORMANCE OF VARIOUS ENVIRONMENTAL RADIATION MONITORS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:20:33.123481+00:00"}
