Five-month recordings of the two BF_3 proportional counters, which were installed about 70cm above and below the snow surface respectively, show that atmospheric neutron fluxes observed at air-snow boundary are between the two expected fluxes at air-soil and air-water boundaries. The attenuation of neutrons in very deep snow cover is intermediate between that in snow cover on soil, that is, a snow-soil interface, and in water, equivalent to a water-water interface. This work suggests an application to estimation of water equivalent depths of a snow cover accumulated on a permanent snow field, or on a glacier, using atmospheric neutrons.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Yamanashi Medical College/Kitami Institute of Technology/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-12-01"}],"displaytype":"detail","filename":"KJ00000012312.pdf","filesize":[{"value":"667.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012312","url":"https://nipr.repo.nii.ac.jp/record/1680/files/KJ00000012312.pdf"},"version_id":"82e9e489-87d1-4b1e-918c-ed0d81ff9b22"}]},"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":"Atmospheric neutrons on snow field at Mizuho Station, Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Atmospheric neutrons on snow field at Mizuho Station, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["388"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-12-01"},"publish_date":"1984-12-01","publish_status":"0","recid":"1680","relation_version_is_last":true,"title":["Atmospheric neutrons on snow field at Mizuho Station, Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:43:54.051771+00:00"}
