A radiation image capturing system comprising: a capturing room (Ra) comprising: a bucky apparatus on which a plurality of portable radiation image capturing apparatuses can be loaded; a radiation irradiating apparatus which is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses loaded on the bucky apparatus; and a detecting unit (55, 60) which detects entry of the portable radiation image capturing apparatus; and a console which is associated with the capturing room (Ra), which is able to control the portable radiation image capturing apparatus detected by the detecting unit (55, 60), and which obtains capturing order information and generates a radiation image (p) based on image data transferred from the portable radiation image capturing apparatus to be associated with the capturing order information; wherein, when long length capturing or simple capturing is not specified in the capturing order information, the console is configured to judge whether the capturing is performed by long length capturing or simple capturing based on the capturing order information; wherein the console allows the plurality of portable radiation image capturing apparatuses in the associated capturing room (Ra) to advance to a capturing possible state when the console judges based on the capturing order information that capturing in the capturing order information is long length capturing which is performed with the plurality of portable radiation image capturing apparatuses loaded in the bucky apparatus; and wherein the console allows only one of the portable radiation image capturing apparatuses in the associated capturing room (Ra) to advance to the capturing possible state when the console judges based on the capturing order information that the capturing in the capturing order information is not the long length capturing. a capturing room (Ra) comprising: a bucky apparatus on which a plurality of portable radiation image capturing apparatuses can be loaded; a radiation irradiating apparatus which is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses loaded on the bucky apparatus; and a detecting unit (55, 60) which detects entry of the portable radiation image capturing apparatus; and a bucky apparatus on which a plurality of portable radiation image capturing apparatuses can be loaded; a radiation irradiating apparatus which is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses loaded on the bucky apparatus; and a detecting unit (55, 60) which detects entry of the portable radiation image capturing apparatus; and a console which is associated with the capturing room (Ra), which is able to control the portable radiation image capturing apparatus detected by the detecting unit (55, 60), and which obtains capturing order information and generates a radiation image (p) based on image data transferred from the portable radiation image capturing apparatus to be associated with the capturing order information; wherein, when long length capturing or simple capturing is not specified in the capturing order information, the console is configured to judge whether the capturing is performed by long length capturing or simple capturing based on the capturing order information; wherein the console allows the plurality of portable radiation image capturing apparatuses in the associated capturing room (Ra) to advance to a capturing possible state when the console judges based on the capturing order information that capturing in the capturing order information is long length capturing which is performed with the plurality of portable radiation image capturing apparatuses loaded in the bucky apparatus; and wherein the console allows only one of the portable radiation image capturing apparatuses in the associated capturing room (Ra) to advance to the capturing possible state when the console judges based on the capturing order information that the capturing in the capturing order information is not the long length capturing.
