Commercial CMOS pixel array for beta and gamma radiation particle counting

We present the response of a Commercial-Off-The-Shelf (COTS) CMOS image sensor to different ionizing particles, with the aim of developing a low cost radiation detector. We first analyze the images obtained by exposing the imagers to X-rays from 55 Fe, gamma and beta particles from 137 Cs. Then the...

Summary:We present the response of a Commercial-Off-The-Shelf (COTS) CMOS image sensor to different ionizing particles, with the aim of developing a low cost radiation detector. We first analyze the images obtained by exposing the imagers to X-rays from 55 Fe, gamma and beta particles from 137 Cs. Then the detector is successfully used to monitor different gamma fluxes produced by the RA6 nuclear research reactor, Argentina, during a startup procedure.
