Development of an integrated CMOS detector for radon activity measurement and neutron dosimetry

The development of pixel CMOS sensors for particle tracking in high energy physics has led to promising applications for dosimetry. We present the last results in electronic monitoring of atmospheric radon with the new system-on-chip AlphaRad, as well as highly efficient detection of fast neutrons with a megapixel Active Pixel Sensor of the MIMOSA generation.
