Analysis of Gamma-Ray Spectra From Soils and Plants: I. Computer Program With Correction for Gain-Shift and Sample Bulk Density¹

ABSTRACT

A computer program and counting techniques used in analyzing complex gamma spectra were developed. The program computes a standard spectrum for each radioisotope based on the bulk density of the sample and then corrects for differences in the energy equation of reference and sample spectra. A solution is then obtained by the method of least-squares.

In addition to a numerical solution, the program provides logarithmic plots of the unknown spectrum, the solution, and the individual components. The approximate execution time is 10 to 15 seconds on an IBM 7094 computer. The program presently has a capacity of 16 standard spectra (512 channels each). This program has been applied successfully to the analysis of complex gamma spectra obtained from soils and plants.
