Dosimetric measurements on the Space Shuttle Missions STS-84, -89 and -91 h
ave been made by the real-time radiation monitoring device III (RRMD-III).
Simultaneously, another dosimetry measurement was made by the Dosimetry Tel
escope (DOSTEL) on STS 84 and by the tissue-equivalent proportional counter
(TEPC) on STS-91. First, the RRMD-III instrument is described in detail an
d its results summarized. Then, the results of DOSTEL and TEPC are compared
with those of the RRMD-III. Also, the absorbed doses obtained by TLD (Mg2S
iO4) and by RRMD-III on board STS-84 and -91 are compared. (C) 2001 Elsevie
