Research at MSF

  • Radiotherapy
  • the use of ionising radiation in the

management of malign and benign diseases

  • Radioprotection
  • assessing and minimising the risk of stochastic

detrimental effects of radiation such as induction of cancer after medical radiation exposures

  • improving preparedness and competence in

Sweden to cope with nuclear emergencies
