PROBLEM TO BE SOLVED: To provide a radiation measuring device.SOLUTION: An imaging section 3 picks up an image. A radiation detector 11 is provided having its detection direction parallel with an optical axis of the imaging section 3, and detects radiation. An angular velocity sensor 4 detects an angular velocity. A pan and tilt determination section 23 calculates velocity data indicative of the direction of the optical axis of the imaging section 3 on the basis of the angular velocity that the angular velocity sensor 4 detects, and determines whether pan or tilt operation is done or not. A calculation section 22 calculates a radiation dose rate from the radiation detected by the radiation detection section 11 through integration using a predetermined time constant, and calculates a radiation dose rate through integration using a time constant shorter than the predetermined time constant when the pan and tilt determination section 23 determines that pan or tilt operation is done. A display section 5 displays the image that the imaging section 3 picks up and the radiation dose rate that the calculation section 22 calculates. |
