We picked thorium series in the emulsion plate, Mod#64; Pl# 9, of KEK- E373 experiment. Five alpha decays from 228Th were observed in the decay chain of thorium series. Among the five α particles tracks, the α-particle from 212Po has higher energy than others and α-particle from 228Th, is observed a little distant from others, are used. We measured the position coordinates of the tracks of the α-particle by using microscope system. The range distribution is plotted as the squared length in the focusing direction, Δz2, versus the squared length in the direction perpendicular to it, Δx2 + Δy2. By fitting those data points with a straight line, we obtained the range of α particles as well as the shrinkage factor of nuclear emulsion. The range of α particles from 228Th is 23.358±0.263 μm. Using the average kinetic energy of α particles from 228Th of 5.400 MeV, the density of the emulsion is obtained by using range-energy program which is based on Barka’s equation, to be 3.745±0.042 g/cm3. On the other hand, for α particles from 212Po, kinetic energy 8.7MeV, is obtained as 48.464±0.355 μm, giving the emulsion density of 3.623±0.026 g/cm3. The density of the nuclear emulsion is determined from the mean of them, 3.684±0.049 g/cm3."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Thorium series"}]}, "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": "Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relat.pdf", "filesize": [{"value": "862 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 862000.0, "url": {"url": "https://meral.edu.mm/record/704/files/Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relat.pdf"}, "version_id": "14447f87-e28e-4eeb-96d7-dfee5c5a9314"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Myingyan Degree College Research Journal", "subitem_volume": "8"}]}, "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": "Khin Than Tint"}]}]}, "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": "2017"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://umoar.mu.edu.mm/handle/123456789/374"}, "item_title": "Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relation Calibration Source", "item_type_id": "21", "owner": "1", "path": ["1582967025340"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000704", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "704", "relation": {}, "relation_version_is_last": true, "title": ["Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relation Calibration Source"], "weko_shared_id": -1}
