The mass attenuation coefficients of Lead for 511 keV , 662 keV, 1173 keV and 1332 keV from gamma sources is determined by using NaI(Tl) scintillation detector. Mass attenuation coefficients measured by experimental methods from this research work are compared to theoretical values from National Institute of Standards and Technology (NIST). The measured values are in agreement with their theoretical values but there is a small difference between experimental and the theoretical results and it has also been noticed that mass attenuation coefficient decreases when the gamma energy increases."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "mass attenuation coefficient"}, {"interim": "NaI(Tl) scintillation detector"}, {"interim": "National Institute of Standards and Technology (NIST)"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2021-01-25"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Nay Min Oo, Dr.pdf", "filesize": [{"value": "28.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 28700000.0, "url": {"url": "https://meral.edu.mm/record/7773/files/Nay Min Oo, Dr.pdf"}, "version_id": "2a6942e6-0b52-4e40-aa76-6dc12b8bf4cd"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "I", "subitem_journal_title": "Meiktila University Research Journal,2020, Vol,XI, No.1", "subitem_pages": "250-255", "subitem_volume": "XI"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Nay Min Oo, Dr"}, {"subitem_authors_fullname": "Khin Soe Moe"}, {"subitem_authors_fullname": "Kay Khaing Oo"}]}]}, "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": "2020-08-31"}, "item_title": "Theoretical and Experimental Determination of Mass Attenuation Coefficient of Lead for Different Gamma Energies", "item_type_id": "21", "owner": "184", "path": ["1608242063591", "1608715482884"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000007773", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2021-01-25"}, "publish_date": "2021-01-25", "publish_status": "0", "recid": "7773", "relation": {}, "relation_version_is_last": true, "title": ["Theoretical and Experimental Determination of Mass Attenuation Coefficient of Lead for Different Gamma Energies"], "weko_shared_id": -1}
