title: Radiation risk of the crew members of the expeditions on the "MIR" station during the 22nd solar activity cycle.
abstract: The radiation risk at the end of the flight was calculated for the members of the main expeditions on the "Mir" station.  It was based on the absorbed dose dynamics data measured by the board dosimeter. The radiation damage models created for standards of the radiation safety of the space flights were used in the calculations.  The analysis of the obtained values of the risk and its dynamics for some cosmonauts are presented in the topic.  The risk values delta P are close to the limited levels given by equation of delta P = 0.6 x 10 x T(-4), [this equation appears also as delta RHrad = 0.6 x 10(-4) x T later in the text] where T--is flight duration in months.
