The absorbed dose and\nthe dose equivalent were evaluated from the linear energy transfer (LET) spectrum of recoils using the\nCR-39 plastic nuclear track detector (PNTD) based on well-established methods in the field of space\nradiation dosimetry. The contributions and spatial distributions of these in the phantom on nominal photon\nexposures were verified as the secondary neutron dose and neutron dose equivalent. The neutron\ndose equivalent normalized to the photon-absorbed dose was 0.261 mSv/100 MU at source to chamber\ndistance 90 cm. The dose equivalent at the surface gave the highest value, and was attenuated to less than\n10% at 5 cm from the surface. The dose contribution of the high LET component of P100 keV/lm\nincreased with the depth in water, resulting in an increase of the quality factor. The CR-39 PNTD is a\npowerful tool that can be used to systematically measure secondary neutron dose distributions in a water\nphantom from an in-field to out-of-field high-intensity photon beam.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ELSEVIER"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"PubMed-ID","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nimb.2015.03.006","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.sciencedirect.com/science/article/pii/S0168583X15002062"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.sciencedirect.com/science/article/pii/S0168583X15002062","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-583X","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
