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 \u03b1 particles tracks, the \u03b1-particle from 212Po has higher energy than others and \u03b1-particle from 228Th, is observed a little distant from others, are used. We measured the position coordinates of the tracks of the \u03b1-particle by using microscope system. The range distribution is plotted as the squared length in the focusing direction, \u0394z2, versus the squared length in the direction perpendicular to it, \u0394x2 + \u0394y2. By fitting those data points with a straight line, we obtained the range of \u03b1 particles as well as the shrinkage factor of nuclear emulsion. The range of \u03b1 particles from 228Th is 23.358\u00b10.263 \u03bcm. Using the average kinetic energy of \u03b1 particles from 228Th of 5.400 MeV, the density of the emulsion is obtained by using range-energy program which is based on Barka\u2019s equation, to be 3.745\u00b10.042 g/cm3. On the other hand, for \u03b1 particles from 212Po, kinetic energy 8.7MeV, is obtained as 48.464\u00b10.355 \u03bcm, giving the emulsion density of 3.623\u00b10.026 g/cm3. The density of the nuclear emulsion is determined from the mean of them, 3.684\u00b10.049 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": ["1582963739756/1582967025340"], "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}
