Abstract:
A gamma-ray spectrum analysis program on Pocket PC was developed for gamma-ray spectrum obtained from a high purity germanium detector. The program has capability in receiving spectrum data directly from CANBERRA series 35 Plus and 10 Plus multichannel analyzers or retrieving recorded data from the Pocket PC memory or the memory card then display a spectrum onthe Pocket PC screen. The developed program is capable of determining peak centroid, peak integral, net peak areas, full width at half maximum (FWHM), peak energy and performing energy calibration as well as isotopes identification. The program was tested for receiving gamma-ray spectrum data from the multichannel analyzer and it was found that the spectrum data transferred with a baud rate between 110 to 19,200 bits per second were entirely correct. Moreover, the developed spectrum analysis program was tested for determining the above peak parameters and peak identification of a gamma-ray spectrum in comparison to the CANBERRA Genie-2000 program. Finally, the program was also tested using an IAEA Test Spectrum having recommended peak parameters. Teh results were found to be very satisfactory. It could be concluded that, especially for field use, the Pocket PC was an alternative to a notebook or a portable microcomputer and could give better portability with less power consumption
