Projects and Funding Granted in the Above Data Acquisition Period:
Competitive projects:
  • EU Contract No. FI16-CT-2003-508842:
    RISC-RAD
  • EU Contract No. 516483 (FI6R) Alpha Risk
Commissioned projects:
  • Philip Morris Products (PMP):
    Prediction of local deposition patterns of multicomponent liquid aerosols
  • British American Tobacco (BAT):
    Modeling deposition of environmental tobacco smoke
Research Topics:
Current research topics:
  • Stochastische Simulation inhalierter Aerosole in der Lunge (Monte Carlo Modelle)
  • Dosimetrie inhalierter Radonzerfallsprodukte (Alphastrahler) in der Lunge und daraus resultierendes Krebsrisko
  • Mikrodosimetrie in Lungenzellen und daraus resultiernde strahlenbiologische Effekte
Future topics (next 5 years):
  • Erweiterung des stochastischen Depositionsmodells auf hygroskopisches Wachstum, Koagulation, Evaporation und dem Transport flüchtiger Komponenten (teilweise gesponsert von PMP and BAT). Damit kann das gesundheitliche Risiko der Inhalation sämtlicher Aerosole und gasförmiger Stoffe in der Umwelt mathematisch beschrieben und ihr gesundheitliches Risiko abgeschätzt werden.
