The purpose of this research was to develop a system that would allow the Health Physics staff of the Nuclear Engineering Department of Rensselaer Polytechnic Institute to conduct wholebody radiation counting of all assigned personnel and to determine if a multiple-crystal arrangement had any benefits over the single-crystal system. The research had three main objectives: to design and construct the electronic hardware necessary to collect data from a series of three NaI(Tl) scintilation crystals; to develop the computer software necessary to interpret this data and calculate concentrations present within those individuals tested; and to interface the Helgeson Wholebody Counter with the Vax 11/750 Computer System. This system includes a Texas Instruments TM990-101M Microcomputer which acts as the main control unit for the operator and as the interface with the Vax computer. Additionally, the final system included a computer interface and data acquisition module and it uses a Digital Equipment Corporation VAX 11/750 Computer System for a majority of the data manipulation. This system, as all wholebody counting systems, is characterized by its ability to detect low levels of radionuclide concentration while maintaining adequate resolution to identify the exact isotopes present within the person being counted.
