Abstract

A POS system checks for radioactive contamination of products without increasing any personnel workload. The POS system includes: a storage means for storing a product code and a radioactivity threshold defined for each product code in association with each other; a barcode scanner; a radioactivity measurement part for measuring radioactivity of a product based on a radiation dose emitted from the product; a comparison means for comparing a radioactivity threshold associated with the product code read by the barcode scanner with a radioactivity measurement value measured by the radioactivity measurement part; and alarm an output means for outputting an alarm when the radioactivity measurement value exceeds the radioactivity threshold. The radioactivity measurement part is arranged at such a position that, when the product exists at a scanning position (A) where the product code is read with the barcode scanner, the radioactivity measurement part detects the radioactivity of the product.
