Simultaneous investigation of galactic cosmic rays on aircrafts and on International Space Station Original Research Article

The galactic cosmic ray component of the space radiation environments at aircraft altitudes and on the International Space Station (ISS) were measured by practically identical silicon active detectors in May–August 2001. The aircraft measurements were performed on commercial flights of CSA airlines, while the measurements on the ISS were part of the “Dosimetric mapping” experiment on ISS. Different cases of comparison are presented in the paper and discussed.
