PROBLEM TO BE SOLVED: To enable selection of a system for matching the irradiation timing with the radiographing timing according to the situation.SOLUTION: A radiographic system comprises a setting unit 260 for selectively setting one of a first control which starts radiographing by detecting the start of irradiation with a radiation detection circuit 221 and a second control which implements control for perform actual radiographing after elapse of a set standby time from the operation of an operation part 250.
