There is provided a radiographic imaging system that has: a radiographic imaging device at which fluoroscopic imaging, that carries out capturing of radiographic images continuously, is possible a radiation irradiating device that irradiates radiation in a pulse form with respect to the radiographic imaging device at a time of fluoroscopic imaging and a controller that controls the radiation irradiating device such that radiation is pulse-irradiated at the radiographic imaging device with a proportion of an irradiation time period of radiation being set within a range of 12.5% to 80% with respect to each frame time period for capturing respective frame images according to a frame rate of fluoroscopic imaging, while capturing of radiographic images is carried out at the radiographic imaging device synchronously with the pulse irradiation.
