DIGITAL COMPUTER AUTOMATION OF BODY BURDEN RETENTION DETERMINATIONS.

Abstract

The report summarizes the task of developing a method of unscrambling a complex homogenization of individual exponential functions. Essentially the problem reduces to, given a set of experimental data known to consist of a series of different exponential decay functions, find each of these functions. The mathematical technique chosen for the investigation was that of non-linear least-squares. Utilizing the method of least squares, a computer program was written, BRAT (Biological Retention Analysis Technique) in Kingstran for the IBM-1620. The program itself was 'taylored' for the USAF Radiological Health Laboratories, although its application to 'fitting' of other compositions with exponential decay is obvious (e.g. the determination of radioactive decay chains by half-life, Bio-assay, etc.).
