PROBLEM TO BE SOLVED: To establish in high precision an optimal dosage irradiated on an interested region of an object. SOLUTION: A radiation image information of a mammo 44 is acquired by a solid detector 46 from radiation rays X irradiated and transmitted from a radiation ray source 74. The detected value detected from a region including the interested region by the solid detector 46 is compared with a prescribed threshold for identifying the interested region, and a detection correction value is calculated based on the region including the identified interested region and the detection value of the interested region. The radiation dosage detected by AEC sensors 49a-49f is corrected by an AEC correction part 78 based on the detection correction value, and irradiation control conditions are determined according to an imaging portion of the object based on the corrected radiation dosage.
