Abstract: Background

Nuclide identification plays an important role in applications of nuclear technology.


This study aims to design a handheld radio gamma spectrometer radionuclide recognizer based on Windows CE to meet the functional requirements of portable radionuclide measurement and identification.


In order to achieve the purpose of quickly and accurately identifying the nuclide, the embedded ARM (advanced RISC machine Cortex-A8) core board of S5PV210 is used as the main control board which has the characteristics of light, easy to operate and low power consumption. The stable performance and rich function of the Windows CE system make it easy to implement data acquisition and processing algorithms. The smoothing effect of Sawicki's first filter, the effect of symmetrical zero area method and nuclide identification were evaluated during the platform testing of the whole system.


The experimental results show that the instrument can identify the basic nuclide quickly and accurately.


The design improves the efficiency of the whole machine and meets the basic requirements.

Key words: Windows CE, Portable nuclide identification instrument, Symmetric zero-area conversion peak-seeking, γ ray spectrometry
