Problems solved by technology

However, the detection of radiation by existing radiation detectors is limited to a single radiation, and the ionizing radiation detection device is affected by the bandwidth of the antenna, which requires an additional DSP module to convert the frequency of the signal, which greatly increases the production cost of the radiation detector.

Moreover, the traditional PIN diode radiation detection device based on a hard substrate is limited by its own conditions and cannot perform radiation detection in a limited space.

The above-mentioned shortcomings are not conducive to the large-scale promotion and use of radiation intensity detectors
