PROPOSAL FOR A NEW RADIATION-DOSE CONTROL-SYSTEM FOR FUTURE MANNED SPACE-FLIGHTS

Radiation risk on a future long-duration manned space mission appears to be one of the basic factors in planning and designing the mission. Since 1988 different active dosimetric investigations has been perform ed on board the MIR space station by the Bulgarian-Russian dosimeter-r adiometer LIULIN and French tissue-equivalent proportional counters CI RCE and NAUSICAA. A joint French-Bulgarian-Russian dosimetry experimen t and the dosimetry-radiometry system RADIUS-MD have been developed fo r the future MARS-96 mission. On the base of the results and experienc e of these investigations a conception for a new radiation dose contro l system for the future orbital stations,lunar bases and interplanetar y space ships is proposed. The proposed system which consists of diffe rent instruments will allow personal radiation control for crew member s, radiation monitoring inside and outside each habitat, analysis and forecasting of the situation and will suggest procedures to minimize t he radiation risk.
