We report on the retrofitting of a standard DP2 environmental radiation monitor replacing the photomultiplier tube with a silicon photomultiplier (SiPM). The use of a SiPM has several advantages for a hand-held radiation monitor, including convenient low-voltage operation and physical robustness. We report the detection efficiency and alpha/beta discrimination performance of the modified probe compared with an unmodified version.
