Pos system and pos system control method

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.

1 . A POS system, comprising:
 a storage means for storing a product code for identifying a product and a radioactivity threshold defined for each product code in association with each other;   a barcode scanner for reading a product code from a barcode attached to a product;   a radioactivity measurement part for measuring radioactivity of the 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   an alarm output means for outputting an alarm when the radioactivity measurement value exceeds the radioactivity threshold,   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.   
     
     
         2 . A POS system according to  claim 1 , further comprising a quantity input means for receiving an input of a quantity of a product,
 wherein when the product is a product subject to radioactivity measurement and the input is carried out through the quantity input means, the input of the quantity is invalidated.   
     
     
         3 . A POS system control method, comprising:
 comparing, by a comparison means, a radioactivity threshold associated with a product code of a product read by a barcode scanner with a radioactivity measurement value of the product measured by a radioactivity measurement part, the radioactivity measurement part being 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 radioactivity of the product, and being configured to measure the radioactivity of the product based on a radiation dose emitted from the product; and   outputting, by an alarm output means, an alarm when the radioactivity measurement value exceeds the radioactivity threshold.
