1. Models for estimating radiation dose and LAR from radioactive fallout: extended dose algorithms for the computational tool LARCalc
Master-uppsats,Sammanfattning : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. LÄS MER
2. 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
3. Odensjön - A new varved lake sediment record from southern Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Annually laminated (varved) sediments provide opportunities to reconstruct climate change and human impact on the environment with high temporal resolution. Depending on the character of the varves, such sediments can provide insight into the delivery of both autochthonous and allochthonous material from the lake and its catch- ment and answer questions regarding both regional and local responses to climate- and land-use changes.

4. Dating lake bottom sediment by searching for 210Pb using gamma-ray spectroscopy
Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : In a collaboration with limnologists at Uppsala University a planar HPGe detector has been used to find 210Pb in lake bottom sediment in hopes of getting an estimation for the sedimentation rate. Using a least squares fit to the data, the sedimentation rate was calculated to 0.08 ± 0. LÄS MER
5. Compilation and evaluation of validations of computer codes for spent nuclear fuel – a review
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : This report describes a systematic review regarding validations of calculations by measurements of isotopic compositions, or decay heat, on spent nuclear fuel, SNF. 15 relevant or otherwise interesting studies, were found. Two reports were chosen among the found studies and analyzed. LÄS MER
