Highly Miniaturized ASIC Radiation Detector

The ability to protect astronauts from harmful radiation particles is a critical enabling element mission design and operation for future human exploration. Currently personal passive devices are worn by all astronauts in order to measure the radiation dose and dose equivalent absorbed by them as required by medical operations. However passive dosimeters can be read out only after landing and they do not provide any alarm capability in case of increased radiation fields.

Both the need of real time monitoring as well as the request for more detailed radiation characteristics for risk assessment, are strongly pushing for new active devices.

A consortium led by ADVEOS Microelectronic Systems (Greece) has been awarded a contract for the TEC-EPS managed TRP activity "Highly Miniaturized ASIC Radiation Detector". ADVEOS will be supported by the Greek Atomic Energy Commission (GAEC, GR), the University of Cyprus (CY) and the National Centre for Scientific Research "Demokritos" (GR).

The development, which will last 18 months, will include design, bredboard and test of a novel, miniaturised active dosimeter, suitable to be deployed in the astronauts suits (including EVA) and throughout habitats. In addition, the team will design, breadboard and test the human interface unit implementing algorithms to process the data acquired by the sensors and provide figures of merit to assess the radiation risk to be accessible to the astronaut on a visual display.
