PROBLEM TO BE SOLVED: To more easily and accurately confirm a positional relationship between the irradiation location with a position confirming radiation, and the irradiation location with a position confirming beam. SOLUTION: To a storage phosphor panel 10 arranged at a specified location, irradiation with the position confirming radiation Xc by an irradiation unit 20, irradiation with a uniform radiation Xb by the irradiation unit 20 to a wider range than the region on the storage phosphor panel 10 irradiated by the position confirming radiation Xc, and the position confirming beam Lp by a confirming beam irradiation unit 30 are performed in this order. Thus, a radiation image showing the positional relationship between the irradiation location with the position confirming radiation Xc and the irradiation location with the position confirming beam Lp is recorded in the storage phosphor panel 10. The radiation image is read from the storage phosphor panel 10 by a radiation image reading unit 201. The positional relationship between the irradiation location with the position confirming radiation and the irradiation location with the position confirming beam is acquired by a positional relationship acquiring unit 202 based on the read radiation image.
