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","filename":"Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relat.pdf","filesize":[{"value":"862 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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"],"publish_date":"2020-03-05","publish_status":"0","recid":"704","relation_version_is_last":true,"title":["Determination of Density of Nuclear Emulsion Plate by using Range- Energy Relation Calibration Source"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-03-24T23:13:45.367434+00:00"}
