Radionuclides are essential in nuclear medicine and therefore new and improved production methods continue to play an important role in ensuring sustainable availability. This thesis focuses on the production of two radionuclides (99mTc and 51Cr) using metal-organic frameworks (MOFs). MOFs are novel porous materials and their potential to be...

The work presented in this thesis provides new data on the behaviour of the binary mixed actinide oxides of the following systems: (Th,Pu)O2, (U,Pu)O2, (Th,U)O2, (U,Am)O2. The results were obtained by performing measurements in a large temperature interval, for some compounds the thermodynamic properties were studied in the range from about 2 to...

Radionuclides are often used in the field of nuclear medicine. For some deceases the use of radionuclides is the best possible care, or even the only means of diagnosis or treatment. For these medical applications high specific activity (high activity per unit of mass) is required. Commonly, medical radionuclides are man-made. They can either be...

Lutetium-177 (177Lu) is a radionuclide with well-established potential in targeted radionuclide therapy (TRNT). 177Lu emits β- particles with a tissue penetration depth of 2 mm, which makes it effective in treating small tumors and causes lower toxicity to nearby healthy cells. The β- emission is also accompanied by gamma ray emission that...

Alpha radionuclide therapy has great potential for effective treatment of metastatic with reduced normal tissue complications. (Pre-clinical) research of alpha radiation of therapy does however suffer from a lack of proper tools for spectroscopy, (micro-) dosimetry and radiobiology. An attempt was made to develop and verify methods for the...

In radionuclide therapy, radioisotopes are used to irradiate tumours from within the body. Usually beta-emitters coupled to tumour-targeting molecules are used, which specifically accumulate at the tumour site. Instead of using beta-emitters, it is also possible to use radionuclides which emit an alpha particle upon decay. Alpha particles have a...

The present thesis’ topic is the biomonitoring of atmospheric trace elements with attention focused on the long-range transported trace elements. The aim was to provide improved understanding of aerosol characteristics under the atmospheric transport dynamics of Central North Atlantic at different altitudes, and also evaluate the usability of...

A radio-fluorogenic (RFG) gel is a polymer gel that can be applied as a 3D radiation dosimeter in radiotherapy. The gel becomes fluorescent in UV light after exposure to high-energy radiation and the intensity of the fluorescence is proportional to the local radiation dose. This radiation-induced fluorescence is permanent, which distinguishes it...

Iron is an essential trace element involved in many processes in the human body. Some disorders like iron deficiency anaemia and haemochromatosis directly result from changes in iron status, while on the other hand iron metabolism changes during illness. Since these adjustments in the iron handling of the body may have consequences for the...

This Thesis focuses on the estimation of the human exposure to air pollutants, and gives special attention to one of the most susceptible groups in the general population - elders. To fulfil the goal the work was conducted following the risk assessment paradigm and, consequently, was divided into 5 tasks: 1) characterization of the indoor air...

The context for this thesis is the concern that people who practice physical activity are more susceptible to air pollution. For the studies presented here, three perspectives of physical activity were considered: in indoor, i) physical activity in fitness centers; in outdoor ii) the use of bicycle in cycle paths; and iii) active transportation....

Böhler, R. (author)
The safety of nuclear power plants is one of the major issues in nuclear materials research. In this context, this PhD thesis presents an original experimental investigation of melting behaviour of several refractory nuclear materials, whose phase diagrams are often still uncertain at temperatures exceeding 2500 K. The physicochemical properties...

The patients with the neuroendocrine tumours (liver, spleen, etc.) often need treatment by the Peptide Receptor Radionuclide Therapy with 177Lu. The amount of 177Lu activity in the body of patients has to be known accurately for assessment of the dosimetry and for evaluation of the effectiveness of the therapy. Whole-body activities at the given...
