PROBLEM TO BE SOLVED: To perform properly charge of a dosimeter and communication, even when using the dosimeter over a long period. SOLUTION: This dosimeter charging communication system is equipped with: an electromagnetic I/F board 3 acquired by arranging an electromagnetic induction coil 4 formed by winding a lead wire in a plurality of times around an insulation plate; and an amplifier circuit 5. The amplifier circuit 5 detects a current signal flowing in the electromagnetic induction coil 4 at the transmission time of an electromagnetic induction antenna of the dosimeter 2 placed on the inside of the electromagnetic induction coil 4 of the electromagnetic I/F board 3, and transmits detection data to an exposure management PC 6. An oscillation signal having a prescribed frequency is modulated by the data transmitted from the exposure management PC 6, and the modulated signal is amplified, and a current corresponding to the amplified signal is made to flow in the electromagnetic induction coil 4. The current signal is received by the electromagnetic induction antenna of the dosimeter 2 as an electromagnetic induction signal. In this case, charging is also performed. Communication with a management device is performed only by placing the dosimeter 2, and charging is performed. COPYRIGHT: (C)2007,JPO&INPIT
