Space Dosimeters Based on CMOS SSPM Technology

The potential threat of harsh radiation environment requires reliable, fault-tolerant sensors capable of providing real-time dosimetry during a space mission, which cannot be achieved by using existing thermoluminescent dosimeter (TLD) technology, especially during an extravehicular activity (EVA). Dose monitoring in real time is especially important for manned low-Earth orbiting spacecraft and interplanetary space vehicles to alert the crew when Solar Particle Events (SPE) increases the radiation level of the spacecraft environment. The development of a tissue-equivalent, CMOS chip-based, personal space dosimeter will meet the demanding requirements for manned space missions.
