Abstract
This system was composed of a personal computer, a liquid scintillation counter and a welltype NaI (Tl) scintillation counter. The radioactivity of smear samples was automatically measured by these counters. The personal computer received raw signals from the counters through an interface of RS-232C. The software for the computer evaluated the surface concentration of each nuclide, and printed out that value along with other items as a report. The software was programmed in Pascal language. This system was successfully applied to routine survey for contamination in our facility.
