<p>PURPOSE:To enable accurate determination of actual exposure to radioactivity in terms of work step including dosage and a total working time, by inputting the name of work item, a work step signal and shift time between work steps into an exposure measuring device. CONSTITUTION:A worker carries an exposure measuring device 1 with a dosage measuring section 10, a receiving section 9, a memory section 12 and the like and when entering a working area, he sets the device with a name of work item input device 3 to start working. A supervisor of the work transmits a work step signal from a work step signal transmitter 4 as each work step shifts. Consequently, time, dosage and a work step number when the work step signal is received are stored into a memory section 12 of the measuring device 1. When the worker sets the measuring device 1 on a leaving device 6 at his leaving from the work site, the contents of the memory section 12 are outputted to a processing computer 8 through the leaving device 6. The computer 8 measures dosage and a total working time in terms of work step for each name of work item based on the informations from measuring devices 1 of all workers.</p> |
