Abstract: Instruments for dosimetry in space radiation environment are introduced briefly. Passive detectors mentioned include luminescent, tracketch, nuclear emulsion, metal foil detectors, bubble detectors and MOSFET dosimeters. Active detectors include silicon semiconductor mainly Liulin-4, silicon telescope including DOSTEL, RRMD,Liulin-5 and CPDS, gas filled detectors including TEPC and R-16 ion chamber, neutron spectrometry including bonner ball spectrometry and phoswich spectrometry. Various instruments and methods are complementary and provide reliable data for space radiation dosimetry.

Key words: Dosimetry-in-Space, Passive, Active
