Radiation image capturing system

A radiation image capturing system comprising:

• a radiation conversion panel for detecting a radiation that has passed through a subject and converting the detected radiation into radiation image information;
• an accumulated exposed radiation dose calculating unit for calculating an accumulated exposed radiation dose applied to said radiation conversion panel;
• and
• a determining unit for comparing the calculated accumulated exposed radiation dose with an allowable accumulated exposed radiation dose for said radiation conversion panel to determine a status of said radiation conversion panel;
• wherein said radiation conversion panel is housed in a radiation detecting cassette with a battery for energizing at least said radiation conversion panel;
• said accumulated exposed radiation dose calculating unit is disposed in said radiation detecting cassette;
• a transmitting unit is connected to said radiation conversion panel, for transmitting at least said accumulated exposed radiation dose to the outside of said radiation detecting cassette by way of wireless communications;
• and
• the accumulated exposed radiation dose calculation unit determines the exposed radiation cumulatively over multiple image capturing cycles.
