<p><P>PROBLEM TO BE SOLVED: To reduce the power consumption of an exposure dose meter used in an enter and leave area management system to a radiation management area and to use a primary battery. <P>SOLUTION: Although generally the conventional secondary battery is used as a power supply of the exposure dose meter (simply called dose meter) carried by a worker in the radiation management area, the cost for replacing the battery is not always low because this type requires a charger or the like. According to the invention, the primary battery is used as the power supply of the dose meter 1, and in order to hold down the power consumption, the power supply is turned on only when it is taken out of a lending device 2, to save the power. <P>COPYRIGHT: (C)2003,JPO</p> |
