Title:
SYSTEM FOR MEASURING RADIATION
Document Type and Number:
Japanese Patent JP3273915
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manage an exposure dose of an individual worker and specify an exposure area in a facility where radiation is handled.
SOLUTION: A facility where radiation is handled is divided to a plurality of areas, and a base station 10 is arranged for each area. The base station 10 communicates with a portable device 12 in the area by radio. The portable device 12 has a communication function by phone and a measurement function for radioactive rays. A host device 18 manages a dose detected by each of the portable devices. In this case, the base station 10 or an exchange 14 judges the area where each portable device is present, so that the host device 18 manages the areas where the portable devices are present as well. At the occurrence of an abnormality, the host device 18 outputs an alarm signal to a part or all of the portable devices 12.
