Mixed radiation fields

The group includes Ivan Kovar, Richard Wagner, Iva Ambrozova, Ondrej Ploc, Jan Kubancak, Katerina Pachnerova Brabcova, Dagmar Peksova (Kyselova formerly) and Martin Kakona. We are looking for answers particularly on the following topics:

  • research of cosmic rays and radiation events in the atmosphere within the research center CRREAT
  • research and monitoring of cosmic radiation onboard the International Space Station and other satellites, on the stratospheric balloons Fik and high altitude observatories
  • monitoring of cosmic radiation onboard aircraft and development of the online database using the Lulin detector and comparison with the neutron monitoring database on Lomnicky stit in High Tatras in cooperation with the Institute of Experimental Physics of the Slovak Academy of Sciences
  • monitoring of atmospheric phenomena in Milesovka using the SEVAN detector in cooperation with the Institute of Atmospheric Physics of the CAS (here - registration requird, send an email to and involvement in the international SEVAN database
  • dosimetry of aircraft crews
  • spectrometry of linear energy transfer in radiotherapeutic beams and their surroundings
  • development of new dosimetric methods and detectors
