RESUMO

Since the end of July 1992, the NAUSICAA system, a low gas pressured tissue equivalent proportional counter, recorded in real time the dose equivalent rate, the absorbed dose rate, the quality factor and the Linear Energy Transfer spectra, aboard the Russian orbital station MIR. The results since the ANTARES mission are presented. Some parameters like the proton flux, the previous solar cycles, the location of the NAUSICAA system inside the station and the South Atlantic Anomaly crossing seem to have an influence on these results. The total dose equivalent (H) during the ANTARES mission (between 1992 July the 30th and August the 10th) was 12 mSv and the total absorbed dose (D) 6.4 mGy with a quality factor (Q) equal to 1.9. The NAUSICAA system gives a good knowledge of LET spectra for the first time in space dosimetry.
