    • Improved procedures for production and purification of 135La from enriched [135Ba]BaCO3 on a 16.5 MeV cyclotron 

      Pedersen, Kristina Søborg; Deville, Claire; Søndergaard, Ursula; Jensen, Mikael; Jensen, Andreas I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-08)
      Lanthanum-135 (<sup>135</sup>La) is a favorable Auger electron emitter with a high Auger electron yield and low gamma emission, making it promising for Auger electron radiotherapy. However, successful application requires reliable and scalable <sup>135</sup>La production. Up to now, metallic natural barium (<sup>nat</sup>Ba) is a commonly used target material, but this material is sensitive to ...

    • PET-CT in the-subarctic region of Norway 2010-2013. At the edge of what is possible? 

      Norum, Jan; Søndergaard, Ursula; Traasdahl, Erik; Nieder, Carsten; Tollåli, Geir; Andersen, Gry; Sundset, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-28)
      Background It is challenging to obtain a similar access to positron emission tomography/computed tomography (PET-CT) within the whole region served. In the subarctic and arctic region of Norway, significant distances, weather conditions and seasonable darkness have been challenging when the health care provider has aimed for a high quality PET-CT service with similar availability to all inhabitants. ...
