PROBLEM TO BE SOLVED: To provide an inexpensive dosimeter responsible to a small size facility, a reading device for reading the dosimeter, an entry administration device using the dosimeter, and an entry administration system. SOLUTION: The dosimeter 1 has a radiation detector 10 detecting radiation, a counter 20 counting signal output from the radiation detector 10, a terminal 30 inputting and outputting signal to external appliances and a power source 40 supplying power, and measures radiation dose by using control signals from the external appliances. Number of members of dosimeter is reduced and assembling man day for assembling members are also reduced, resulting in a large effect of improving reliability. COPYRIGHT: (C)2005,JPO&NCIPI
