AB In order to facilitate the technologist’s work, a simple method of counting the activity of wipe test samples for contamination control in the nuclear medicine department has been developed. A scintigraphic three-minute image is directly obtained from the uncollimated gamma camera with the help of a homemade plexiglas template which holds the samples. A computer program analyzes this image, simultaneously calculates the activity of a maximum of 12 samples after correcting for the background, and expresses the result as a percentage of the predetermined maximum permissible activity. The results are stored on diskette and a hard copy is produced for permanent record keeping.
