Abstract:

The digital computer, automatic unscrambling of the gamma-ray spectra from a whole-body counter is accomplished by a Fortran II computer code suitable for the IBM-1620 or similar machines. The code is designed for specific use with the USAF Radiological Health Laboratories whole-body counting facility but might be used in any similar spectral analysis operation. The USAF facility is described. The code will determine relative intensities of any eight or less internal emitters in a complex spectrum, so long as the separate spectra of these emitters are contained in the input. The reduction of the complex spectra is accomplished by the LeastSquares method. Application of the code to sample spectra of known isotopic compositions for dosed phantoms and invivo human testing yields maximum errors of the order of three to four percent with respect to peak analysis methods.
