The spectrometer has been used to measure ^\u003c14\u003eC concentrations of natural samples, as well as ^\u003c14\u003eC ages of geological and archeological samples. The Tandetron spectrometer measures ^\u003c14\u003eC/^\u003c13\u003eC ratios of carbon prepared from carbonaceous samples. The ratio of a young samples (^\u003c14\u003eC ages younger than several thousand years old) is routinely measured with a precision of ±1%, using a C-Ag mixture target containing only 2-5 mg of carbon, in a measurement lasting about 4 hours. Errors for older samples become larger, because of the smaller number of ^\u003c14\u003eC counts. The ^\u003c14\u003eC background level of the spectrometer, estimated by using old natural graphite, it about 3x10^\u003c-16\u003e in ^\u003c14\u003eC/^\u003c12\u003eC ratio. The Tandetron spectrometer has been applied to measure ^\u003c14\u003eC concentrations, Δ^\u003c14\u003eC, of annual rings (1945-1983) from a Kiso hinoki tree (Japanese Cypress), to investigate the annual Δ^\u003c14\u003eC variation of the atmospheric CO_2 ; the cause of variation could be addition of ^\u003c14\u003eC produced by nuclear weapon tests in late 1950\u0027s to early 1960\u0027s. The ^\u003c14\u003eC concentrations in pine needles, collected at the Higashiyama Campus of Nagoya University, have also been measured since 1983. The results in our ^\u003c14\u003eC measurement of pine needles are described in the present study, focusing on the annual changes in Δ\u003c14\u003eC values of the atmoshperic CO_2,and on the effect upon ^\u003c14\u003eC concentrations for pine needles of a local ^\u003c14\u003eCO_2 emission from incineration of radioactive organic solvent wastes containing ^\u003c14\u003eC, which have been produced by biochemical experiments with ^\u003c14\u003eC tracer, at the Radioisotope Center in the Higashiyama Campus of Nagoya University.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.2.104", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110000475776/", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中村, 俊夫"}], "nameIdentifiers": [{"nameIdentifier": "79458", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "79459", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中井, 信之"}], "nameIdentifiers": [{"nameIdentifier": "79460", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakai, Nobuyuki"}], "nameIdentifiers": [{"nameIdentifier": "79461", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "古川, 路明"}], "nameIdentifiers": [{"nameIdentifier": "79462", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Furukawa, Michiaki"}], "nameIdentifiers": [{"nameIdentifier": "79463", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000187507.pdf", "filesize": [{"value": "414.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 414100.0, "url": {"label": "KJ00000187507.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11317/files/KJ00000187507.pdf"}, "version_id": "3fd4c3e7-8739-4ace-869a-e9de64955dc0"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "名古屋大学東山キャンパス内の松葉の\u003c14\u003e^C濃度測定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "名古屋大学東山キャンパス内の松葉の\u003c14\u003e^C濃度測定"}]}, "item_type_id": "9", "owner": "1", "path": ["1220"], "permalink_uri": "https://doi.org/10.18999/sumrua.2.104", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-04-26"}, "publish_date": "2010-04-26", "publish_status": "0", "recid": "11317", "relation": {}, "relation_version_is_last": true, "title": ["名古屋大学東山キャンパス内の松葉の\u003c14\u003e^C濃度測定"], "weko_shared_id": null}
