PROBLEM TO BE SOLVED: To provide a radiograph which permits electric charge remaining in a radiation detection element to be accurately removed while restraining wasteful power consumption. SOLUTION: The radiograph 1 has a plurality of radiation detection elements 7 causing the electric charge in accordance with the dose of applied radiation, an amplification circuit 18 converting the electric charge read from the radiation detection elements 7 through a signal line 6 to image data D, a bias power source 14 applying bias voltage to each of the radiation detection elements 7 through the bias line 9, electric current detection means 43 to detect electric current flowing in the bias line 9, dose computing means 22 to compute the dose of applied radiation on the basis of a value of electric current detected by the electric current detection means 43 at the time when the radiation is applied, and control means 22 to set resetting conditions of each of the radiation detection elements 7 on the basis of the computed dose and reset each of the radiation detection elements 7 in accordance with the set resetting conditions.
