POINT-OF-SALE SYSTEM THAT MEASURES RADIOACTIVITY OF A PRODUCT

摘要

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.

主权项

1. A point of sale (POS) system, comprising:
a memory configured to store a product code for identifying a product and a radioactivity threshold which is the product information defined for each product code in association with each other; a barcode scanner configured to read the product code from a barcode attached to the product; a radioactivity measurement part configured to measure radioactivity of the product based on a radiation dose emitted from the product; a processor configured to compare a radioactivity threshold associated with the product code read by the barcode scanner with a radioactivity measurement value measured by the radioactivity measurement part; an alarm output part configured to output an alarm when the radioactivity measurement value exceeds the radioactivity threshold; and wherein the radioactivity measurement part is arranged at such a position that, when the product exists at a scanning position where the product code is read with the barcode scanner, the radioactivity measurement part detects the radioactivity of the product; wherein the radioactivity measurement part is constructed as a component separate from the barcode scanner; and wherein the radioactivity measurement part and the barcode scanner are fixed to a POS terminal or are fixed to a bagging counter.
