Abstract
Two new, miniaturised scientific radiation monitoring payloads are presented prior to its flight on the TechDemoSat-1 Spacecraft, capable of monitoring the space radiation environment and its effects on radiation sensitive devices. MuREM and SSTL RM carry RADFET dosimeters, dose rate sensitive photodiodes and PIN diode particle detectors. SSTL RM is also connected to external RADFET sensors placed around the spacecraft, whilst MuREM carries a radiation effects payload consisting of COTS devices which will be monitored whilst exposed to the space radiation environment. © 2011 IEEE.
