ABSTRACT: At present, the portable radioactive aerosol measuring instrument prototype mainly adopts the cumulative measurement method, which requires personnel to regularly replace the filter, which is not conducive to online long-term measurement. Therefore, this paper designs a portable radioactive aerosol measuring instrument prototype that is easy to carry, high-precision, low-power, and small in size. Firstly, the internal and external structures were miniaturized. Secondly, low-power design was adopted for the hardware. Finally, based on the characteristics of radioactive aerosol particles, algorithm design and software design were carried out. The stability, airtightness, paper feeding accuracy, signal quality, and multi-channel performance of the instrument were verified through testing. The final result shows that the instrument can operate stably and continuously.
