The mixed air was mutually reacted in the Pd-coated catalyst column to give water, followed to another molecular sieve column to adsorb the newly synthetic water for the evaluation of HT concentrations. The tritium concentration in each water fraction and in the collected precipitations was counted by the liquid scintillation method using Aquasol II scintillator. The results, summarized in Fig. 3 and Table 2, obviously show that the HT concentration is maintaining almost constant value of 1-2 pCi/m^3 -air during all seasons. On the other hand, the HTO concentration is remarkably influenced by the collecting months; having lowest tritium concentration in winter while the highest concentration (corresponding to about 3.0 pCi/m^3 -air) appears in July and followed by the gradually decreasing tendency from the end of summer. In the case of precipitations, the average tritium concentration was evaluated to be 76 pCi/l for all precipitations collected from July 1983 to June1984 in Niigata area. These fundamental data will serve for the hydrologic applications of tritium like the estimation of exchange period of groundwaters, as well as the assessment of background tritium level before the operation of nuclear electric power stations.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "161946", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hashimoto, Tetsuo"}]}, {"nameIdentifiers": [{"nameIdentifier": "161947", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Higuchi, Yasushi"}]}, {"nameIdentifiers": [{"nameIdentifier": "161948", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sato, Osamu"}]}, {"nameIdentifiers": [{"nameIdentifier": "161949", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Aoki, Shigeru"}]}, {"nameIdentifiers": [{"nameIdentifier": "161950", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tonouchi, Shigemasa"}]}, {"nameIdentifiers": [{"nameIdentifier": "161951", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sotobayashi, Takeshi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学積雪地域災害研究センター"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183327", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03877892", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "橋本, 哲夫"}], "nameIdentifiers": [{"nameIdentifier": "161940", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "樋口, 靖"}], "nameIdentifiers": [{"nameIdentifier": "161941", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "佐藤, 修"}], "nameIdentifiers": [{"nameIdentifier": "161942", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "青木, 滋"}], "nameIdentifiers": [{"nameIdentifier": "161943", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "殿内, 重政"}], "nameIdentifiers": [{"nameIdentifier": "161944", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "外林, 武"}], "nameIdentifiers": [{"nameIdentifier": "161945", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "6_73-82.pdf", "filesize": [{"value": "662.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 662700.0, "url": {"label": "6_73-82.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28175/files/6_73-82.pdf"}, "version_id": "67250da2-eaac-4716-80d6-b06894dd6bad"}]}, "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": "液体シンチレーション法による大気中および降水中のトリチウム濃度測定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "液体シンチレーション法による大気中および降水中のトリチウム濃度測定"}, {"subitem_title": "液体シンチレーション法による大気中および降水中のトリチウム濃度測定", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1577"], "permalink_uri": "http://hdl.handle.net/10191/39040", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-03"}, "publish_date": "2016-03-03", "publish_status": "0", "recid": "28175", "relation": {}, "relation_version_is_last": true, "title": ["液体シンチレーション法による大気中および降水中のトリチウム濃度測定"], "weko_shared_id": null}
