Relativistic electron fluxes and dose rate variations observed on the international space station

The paper presents observations of relativistic electron precipitations (REP) on the International Space Station (ISS) obtained by three Bulgarian-built instruments flown in 2001 and 2008–2010. The first data are from the Liulin-E094 instrument flown in May–August 2001 inside the US laboratory modul...

Summary:The paper presents observations of relativistic electron precipitations (REP) on the International Space Station (ISS) obtained by three Bulgarian-built instruments flown in 2001 and 2008–2010. The first data are from the Liulin-E094 instrument flown in May–August 2001 inside the US laboratory module of the ISS. Next the time profiles of the REP-generated daily fluences and the absorbed doses at the orbit of ISS during the period February 2008–August 2010 are analyzed in dependence of the daily Ap index and compared with the daily relativistic electron fluence with energies of more than 2MeV measured by the GOES. The REP in April 2010 being the second largest in GOES history (with a >2MeV electron fluence event) is specially studied. ► We report observations of relativistic electrons on ISS. ► Data are obtained by Bulgarian build Liulin type instruments. ► It is obtained that relativistic electrons on ISS are common phenomena.
