Abstract:
1. A method for combining the individual spectral data from a plurality of ionizing radiation detectors to produce a single combined spectrum radiation analysis, the method comprising: providing a first computing device, wherein the first computing device accepts input from a plurality of calibrated spectroscopic detectors; detecting, using the spectroscopic detectors, the radiation level from a radioactive source; computing spectral histograms for at least two of the spectroscopic detectors; separating the photopeak counts from the underlying continuum counts using baseline estimation for each spectral histogram to create a respective peak spectral array; rebinning each peak spectral array to conform to a common energy calibration; convolving the rebinned peak spectral arrays to create a convolution array; redistributing counts, according to the local convolution array distribution, in each rebinned spectral array over a symmetrical energy region proportional to the respective photopeak shape calibration at the channel energy; summing the redistributed counts to obtain the combined spectrum; and preparing a report related to the combined spectrum for display to a user.
