6. Luftfiltermätningar av atmosfärisk radioaktivitet : Mätningar av luftfilter med gammaspektroskopi
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Projektet handlar om att mäta atmosfärisk radioaktivitet och utforma en procedur för hur en luftfiltermaskin och en detektor kan användas för att samla in och mäta atmosfärisk radioaktivitet. Det innehåller luftinsamling, förberedelse av prov, mätning och analys. LÄS MER
7. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets
L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. LÄS MER
8. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. LÄS MER
9. Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden : Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden
Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Technological advancement and the quest for power have gradually contaminated our environment, as industrialization, agriculture, and nuclear activities progressed. In the year 1986, a terrible nuclear incident occurred in Ukraine, in which the nuclear reactor exploded. LÄS MER
10. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase
Master-uppsats, Lunds universitet/SjukhusfysikerutbildningenSammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER
