摘要：

A peak fraction method of interpretation of gamma-spectra is described. A computer technique is proposed for work under varying conditions which consists of successive applications of a series of procedures. Curves are smoothed and calibrated peak fraction areas are calculated. For peak fraction calibration, the points of inflection on a third order approximation curve are used. The shape of the peak fractions is checked with normalized Gaussian curves. This method permits work without a catalog of standard spectra and gives better results than spectrum stripping in the lower energy region of composite spectra. It is suitable for the interpretation of trace elements in biological materials. © 1968, American Chemical Society. All rights reserved.
