Chapter 1 is concerned with the ionizations by the alpha-, beta-, and gamma-radiations from the atmosphere and the ground. The specially designed ionization chamber and the plastic wall ionization chamber are used for measuring the rate of ion pair production by the beta-, and gamma-radiations respectively. The charcoal trapping method is used for measuring the rate of ion pair production by the alpha-radiation. The survey was carried out at 32 points in and around Nagoya City. The beta-radiation plays the largest contribution for the ionization of the air near the ground, and the gamma-radiation including cosmic-ray is the next. The rate of ion pair production due to the alpha-radiation in the atmosphere is almost 1 J on the average. The contribution of the low energy radiation below 40 KeV for the ionization of the air close to the ground is almost the same with that of the alpha-radiation. Chapter 2 is concerned with the properties of the radioactive ions. The energy-spectra of alpha-particles radiated from the radioactive ions in the three ranges of critical mobility were measured. The results showed that the radioactive ions of which critical mobilities being 4.4 cm^2/sec V and 0.7 cm^2/sec V carry only RaA, and those of which critical mobility being 0.2 cm^2/sec V carry not only RaA but also RaB and RaC. The results of simultaneous measurements show that the radioactive ions of which critical mobility being 4.4 cm^2/sec V only are free from any kind of condensation nuclei. The mean life of radioactive ion in the range described above is 23 sec on the mountain top, and is 1.3 sec on the campus inside a big city.", "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.17.2.125", "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": "Kawano, Minoru", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "103199", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ikebe, Yukimasa", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "103200", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakashima, Yoshiyuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "103201", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimizu, Kuniyasu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "103202", "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": "2021-02-04"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "17-2-01.pdf", "filesize": [{"value": "5.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 5400000.0, "url": {"label": "17-2-01.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/31270/files/17-2-01.pdf"}, "version_id": "fd4624ab-40f7-4208-a7e1-a2fb05d93b2f"}]}, "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": "Some properties of naturally occuring radiations and radioactive ions in the atmosphere", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Some properties of naturally occuring radiations and radioactive ions in the atmosphere", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2625"], "permalink_uri": "https://doi.org/10.18999/memfenu.17.2.125", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-02-04"}, "publish_date": "2021-02-04", "publish_status": "0", "recid": "31270", "relation": {}, "relation_version_is_last": true, "title": ["Some properties of naturally occuring radiations and radioactive ions in the atmosphere"], "weko_shared_id": -1}
