1. Decay Chains of Fast Alpha Emitters in the Actinide Region
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

2. Uranium nitride synthesis by gas/gas reaction of UF6 and NH3
University essay from KTH/FysikAbstract : This thesis project aims to develop an innovative technique for the production of high-purity uranium nitride (UN) through the ammonolysis of fluorides. The desired objective is to perform a controlled gas/gas reaction between uranium hexafluoride (UF6) and ammonia (NH3) at 800°C. READ MORE

3. Experimental studies of radiation damage in uranium nitride
University essay from KTH/FysikAbstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

4. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking
University essay fromAbstract : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. READ MORE

5. Assessing the controls of the fluoride concentrations in the groundwater of Gothenburg area
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : The human uptake of fluoride can promote healthy teeth in low concentration (1.5 mg/l). Drinking water is a major route to which we humans are expose to fluoride intake. READ MORE
