Claim 9:
10. A method for positioning a portion to be irradiated with radiation in a sample using a radiation detection device including an optical microscope configured to observe a sample, an irradiation unit that irradiates the sample observed by the optical microscope with the radiation, and a detection unit that detects radiation generated from the sample irradiated with the radiation, the method comprising:
adjusting a relationship between a focal position of the optical microscope and a position of the sample such that the optical microscope is focused on one portion of the sample;
sequentially changing a position, on which the optical microscope is to be focused, on the sample;
calculating a distance from a predetermined base point to the surface of the sample at the changed position on the sample according to the adjusted focal position;
creating a partial image captured by the optical microscope at the changed position on the sample in a state in which adjustment of the relationship is performed for focusing;
creating a sample image including information in which the calculated distance is associated with each of a plurality of portions of the sample by combining a plurality of created partial images; and
positioning the portion to be irradiated with the radiation in the sample, on the basis of the sample image.
