We present the response of a Commercial-Off-TheShelf(COTS) CMOS image sensor to different ionizing particles,with the aim of developing a low cost radiation detector. Wefirst analyze the images obtained by exposing the imagers to Xraysfrom 55Fe, gamma and beta particles from 137Cs. Then thedetector is successfully used to monitor different gamma fluxesproduced by the RA6 nuclear research reactor, Argentina, duringa startup procedure.
