As a reference, certified reference materials IAEA-448 and IAEA-RGU-1 were used. To calibrate the NaI (Tl) detector, standard gamma source 152Eu (Spectrum Technique, USA) was utilized. Calibration ranges from 122 keV to 1408 keV. All the measurements were performed at the Experimental Nuclear Physics Lab, Department of Physics, University of Mandalay. All possible expected radionuclides from Uranium decay chain were investigated. Radionuclides from measured spectra of IAEA-448 and IAEA-RGU-1were also examined. It can be observed that 226Ra (186keV), 214Pb (241keV), 214Pb (295keV). 214Pb (351keV) and214Bi (609keV) are contained in the certified reference materials.It can also be observed that net area of each Radionuclide in IAEA-448 and IAEA-RGU-1 reference samples are reliable on their present activity and gamma emission probability."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Gamma Spectroscopy"}, {"interim": "Certified Reference Materials"}, {"interim": "Radionuclides"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-10-01"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Determination of Radionuclides in Uranium Decay Chain by Gamma Spectroscopy.pdf", "filesize": [{"value": "476 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 476000.0, "url": {"url": "https://meral.edu.mm/record/5560/files/Determination of Radionuclides in Uranium Decay Chain by Gamma Spectroscopy.pdf"}, "version_id": "ff32ee80-5a5a-4fa7-902b-2d95a77ce2b6"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "3", "subitem_journal_title": "University of Mandalay, Research Journal", "subitem_pages": "120 - 127", "subitem_volume": "11"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"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": "2020-05-01"}, "item_title": "Determination of Radionuclides in Uranium Decay Chain by Gamma Spectroscopy", "item_type_id": "21", "owner": "23", "path": ["1582963739756", "1582967025340"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000005560", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-10-01"}, "publish_date": "2020-10-01", "publish_status": "0", "recid": "5560", "relation": {}, "relation_version_is_last": true, "title": ["Determination of Radionuclides in Uranium Decay Chain by Gamma Spectroscopy"], "weko_shared_id": -1}
