So, samples with dimension [76mmx76mmx0.9mm] and [76mmx76mmx1mm] are made. Then the photon attenuation after passing through the investigated samples is carried out by using NaI detector. The experimental arrangements include 2\"x2\" NaI (Tl) scintillation detector (Model No. 2M2/2), the photomultiplier tube base (digiBASE) with USBconnection and MAESTRO-32 gamma detection software installed in a computer. 137Cs source is used for the incident photon beam. By analyzing the spectra the photon intensities before and after the samples are obtained. From these, the attenuation coefficients and the buildup factorsfor the given samplescan be calculated by using the relative methods."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "buildup factors"}]}, "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": "BUILDUP FACTORS FOR GAMMA ATTENUATION.pdf", "filesize": [{"value": "420 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 420000.0, "url": {"url": "https://meral.edu.mm/record/267/files/BUILDUP FACTORS FOR GAMMA ATTENUATION.pdf"}, "version_id": ""}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "1", "subitem_journal_title": "Yadanabon Universithy 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": "Wunna Ko"}]}]}, "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": "2014"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://oar.ydbu.edu.mm/handle/123456789/147"}, "item_title": "Buildup factors for gamma attenuation in some shielding materials", "item_type_id": "21", "owner": "1", "path": ["1582963788001/1582966489046"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000267", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "267", "relation": {}, "relation_version_is_last": true, "title": ["Buildup factors for gamma attenuation in some shielding materials"], "weko_shared_id": -1}
