1. 26. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

   Författare :Gustav Grafström; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low energy; Radiobiology; dosimetry; cell model; Radiofarmaceutisk teknik; Radiopharmaceutical technology; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; animal model;

   Sammanfattning : Background: During the last 20 years both in vitro and in vivo models have been developed for studies of the cell killing characteristics of low energy electrons, e.g. Auger electrons. This thesis deals with radiobiological effects of radiation from indium isotopes in V79 cells in vitro (Paper I-III) and the rat testis in vivo (Paper IVV). LÄS MER

3. 27. Methods for image-based dosimetry and radiobiological modelling in radionuclide therapy

   Författare :Johan Gustafsson; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide therapy; dosimetry; biologically effective dose; 177Lu-DOTATATE;

   Sammanfattning : In radionuclide therapy (RNT), radioactive pharmaceuticals are administered for therapeutic purposes. Dosimetry, i.e. the estimation of the absorbed dose to various targets, can potentially lead to a better understanding of the therapeutic effects in RNT and allow for individualization of the therapy.

4. 28. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

   Författare :Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

   Sammanfattning : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. LÄS MER

5. 29. Radiofrequenz-Pulse in der lokalisierten STEAM-Spektroskopie

   Författare :Gunther Helms; Lund Medicinsk strålningsfysik; []
   Nyckelord :;

   Sammanfattning : By definition, radiofrequency (RF) pulses are the pivotal elements of NMR pulse sequences. Vice versa, the effect of a particular pulse on the evolution of magnetization will depend on the context of the sequence. LÄS MER

7. 30. Internal dosimetry. Macroscopic, small-scale and microscopic perspectives

   Författare :Cecilia Hindorf; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; B-cell lymphoma; Radioimmunotherapy; Radionuclide therapy; Internal dosimetry; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

   Sammanfattning : Internal dosimetry deals with the assessment of absorbed dose for radionuclides distributed inside the body. The absorbed dose is in its turn used for correlation with the biological effect caused by the irradiation. LÄS MER
