title: "Mir" radiation dosimetry results during the solar proton events in September-October 1989.
abstract: Using data from dosimetry-radiometry system "Liulin" on board of "Mir"-space station the particle flux and doserate during September-October, 1989 has been studied.  The orbit of the station was 379 km perigee, 410 km apogee and 51.6 degrees inclination.  Special attention has been paid to the flux and doserate changes inside the station after intensive solar proton events (SPE) on 29 of September, 1989.  The comparison between the doses before and after the solar flares shows increase of the calculated mean dose per day by factor of 10 to 200.  During the SPE on the 29 of September the additional dose was 310 mrad.  The results of the experiment are compared with the data for the solar proton fluxes obtained on the GOES-7 satellite.
