Computer Program for Activity Determinations in the USAFSAM Whole-Body Counter

Abstract

The USAFSAM whole-body counter requires very precise calibration if it is to determine with accuracy the amounts of specific radioisotopes contained in a human body. Rigorous detection efficiencies for the isotopes of interest must be established in all channels of the instrument and frequently monitored. Calculations for accurate calibration and sample determination involve length matrix operations which are too time-consuming for repetitive manual procedures. Presented is a computer program for the accurate computation of the amount of radioactive material, as measured by the USAFSAM whole-body counter, in a human body. The approach and development of the program and mathematical techniques are discussed, and all factors involved in the program are described in detail.
