The gamma sources used are 22Na (511 keV and 1275 keV), 137Cs (662 keV) and 60Co (1173 keV and 1332 keV). In this research, three beam geometrical configurations (narrow beam, semi-broad beam and broad beam) were constructed by six lead collimators. The main focus of this study is to determine the attenuation properties of two organic liquids containing H, C and O. The mass attenuation coefficients and the atomic cross - sections of two organic liquids were determined theoretically by using the mixture rule and experimentally by using gamma-ray attenuation technique. The experimental mass attenuation coefficients were found to be in nearly agreement with the theoretical values in narrow beam and first semi-broad beam geometries. The total atomic cross-sections of two organic liquids were calculated."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "two organic liquids"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Two Gamma Spectrometric Parameters.pdf", "filesize": [{"value": "350 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 350000.0, "url": {"url": "https://meral.edu.mm/record/554/files/Two Gamma Spectrometric Parameters.pdf"}, "version_id": "3230f5ac-df82-4634-8e86-22532d9ff3e9"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "1", "subitem_journal_title": "University of Mandalay Research Journal", "subitem_volume": "5"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Aye Myat Mon"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2012"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://oar.ydbu.edu.mm/handle/123456789/189"}, "item_title": "Two gamma spectrometric parameters of two organic liquids with various beams geometry collimators", "item_type_id": "21", "owner": "1", "path": ["1582963788001/1582966489046"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000554", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "554", "relation": {}, "relation_version_is_last": true, "title": ["Two gamma spectrometric parameters of two organic liquids with various beams geometry collimators"], "weko_shared_id": -1}
