Space Radiation and Plasma Monitoring:Rationale
ESA Space Environment &Effects Analysis Section
● Effects of the space radiation and plasmaenvironment are varied and complex:instrument “background”, component &material degradation, SEP, spacecraftanomalies, ...
● New technologies → new problem areas
● Modelling: Need for continuous measurementswith adequate spatial, energy and particlespecies coverage

Radiation Environment Monitor (REM)
STRV-1b
Two units:
● STRV-1b microsatellite(1994 - 98)
● MIR space station(1994 - 96)
