This work presents a high-resolution, high-confidence, and high-temperature-stabilization prototype environmental radiation monitoring system (ERMS) with integrated digital filter, peak-finding algorithms, and real-time analyses. Through measuring 137Cs and 60Co radiation sources with the same NaI(Tl) detector, the features of the digital multichannel analyzer (DMCA) in our system, including throughput, energy resolution, and peak shape, were compared with those of a commercial instrument, namely the DSPEC jr 2.0 from ORTEC, USA. The results indicate that the full-width at half-maximum (FWHM) and peak heights obtained with our DMCA are better than those obtained with the DSPEC jr 2.0 up to 12%. The ERMS also integrates a solar power supply, multimodal data transmission, and a weather channel, thus facilitating its deployment in boundary areas or far islands for monitoring and forecasting radioactive propagation. Therefore, the proposed configuration system is highly promising in terms of performance and low cost of maintenance.

环境辐射监测系统的可靠配置

这项工作提出了一种高分辨率、高可信度和高温稳定的原型环境辐射监测系统 (ERMS)，具有集成的数字滤波器、寻峰算法和实时分析。通过使用相同的 NaI(Tl) 探测器测量 137Cs 和 60Co 辐射源，将我们系统中数字多道分析仪 (DMCA) 的特性，包括吞吐量、能量分辨率和峰形，与商用仪器的特性进行了比较，即美国ORTEC的DSPEC jr 2.0。结果表明，使用我们的 DMCA 获得的半峰全宽 (FWHM) 和峰高比使用 DSPEC jr 2.0 获得的高 12%。ERMS 还集成了太阳能电源、多模式数据传输和天气通道，从而促进其部署在边界地区或远岛以监测和预测放射性传播。因此，所提出的配置系统在性能和低维护成本方面非常有前途。
