Abstract: A radiation image capturing system includes a capturing room and a console. The capturing room includes a bucky apparatus, a radiation irradiating apparatus and a detecting unit. A plurality of portable radiation image capturing apparatuses can be loaded on the bucky apparatus. The radiation irradiating apparatus is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses. The console is associated with the capturing room and obtains capturing order information. The console allows the portable radiation image capturing apparatuses to advance to a capturing possible state when the console judges that capturing in the capturing order information is long length capturing. The console allows only one of the portable radiation image capturing apparatuses to advance to the capturing possible state when the console judges that the capturing is not the long length capturing.
