As fundamental works, the mean free path length, energy loss and penetration ranges of electrons with a few keV in aluminum and stearic-acid monomolecular layers were measured. Gas multiplication factors in proportional counters with cylindricaland rectangular-cathodes which have been extensively used in our works were examined experimentally and theoretically. Position-sensitive proportional counters of a charge division type were examined and found some new applications. The absolute radioactivity of [β]- and [γ]-ray emitting nuclide sources can be determined by applying 4[π][β]-[γ] coincidence absorption method. The sources for 4[π][β] counting using an aluminum compound which brought less self-absorption of [β]-rays were prepared successfully. Electrical conductivity of the thin film for source backing was evaluated. A new method with a position-sensitive proportional counter was developed for absolute activity measurement of gaseous samples. There are now intensive needs for tritium surface contamination monitor and gas monitor. Recently, we succeeded in developing a proportional counter with air as counting gas, named air proportional counter, for [β]-ray detection and applied it to tritium surface contamination monitor and gas monitor. A hybrid spark chamber was developed to obtain the image of geometrical distribution of [β]-ray emitting nuclides.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.39.2.324", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Watanabe, Tamaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102021", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mori, Chizuo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102022", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyahara, Hiroshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102023", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Aoyama, Takahiko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102024", "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": "2020-10-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "39-2-03.pdf", "filesize": [{"value": "8.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 8700000.0, "url": {"label": "39-2-03.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/30753/files/39-2-03.pdf"}, "version_id": "9550d15e-0363-49c0-a734-50f073569c56"}]}, "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Measurement of radiation and radioactivity", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Measurement of radiation and radioactivity", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2553"], "permalink_uri": "https://doi.org/10.18999/memfenu.39.2.324", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-10-29"}, "publish_date": "2020-10-29", "publish_status": "0", "recid": "30753", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of radiation and radioactivity"], "weko_shared_id": -1}
