摘　　要：The calibration detector of a gamma ray monitor （GRM） is designed to detect alpha particles from 241 Am and to send out the coincidence signal to the GRM X-ray detector. The silicon photomultiplier （SiPM）, as a novel photon device, is a good candidate to convert alpha-exciting fluorescent photons into electric signals. Three types of SiPMs from SSPM and MPPC, each having an active area of 3 mm×3 mm, were compared in the matter of the spectra from low-intensity light, dark count, crosstalk probability and I -V curve. The temperature coefficient of SSPM-0710G9MM was also characterized. The application of a SiPM on the GRM has been proved to be feasible.The calibration detector of a gamma ray monitor （GRM） is designed to detect alpha particles from 241 Am and to send out the coincidence signal to the GRM X-ray detector.
