Abstract：
In order to avoid unnecessary or unallowable exposure in the gamma-neutron mixed field, the radioactive-contact person should know the radiation environment at any time by himself when he is working. A new kind of pocket radiation doserate monitor (chirper) based on silicon PIN photodiode as detector is designed. It can be used to monitor the gamma doserate in the order of 1 mrem/h and the neutron doserate in the order of 10 mrem/h simultaneously. In this paper, the detector selection, the circuit design, the construction and the performance of the chirper prototype are described.
