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 55Fe, gamma and beta particles from 137Cs. Then the detector is successfully used to monitor different gamma fluxes produced by the RA6 nuclear research reactor, Argentina, during a startup procedure.
