METHOD AND DEVICE FOR CREATING SPATIAL RADIATION DOSE DISTRIBUTION MAP

PROBLEM TO BE SOLVED: To provide radiation dose distribution map device displayed overlappedly on a map by measuring a radiation dose in a relatively narrow area, such as a town, a village or a neighborhood association unit, and classifying the radiation doses according to the magnitudes of the radiation doses by color.SOLUTION: A GPS measures latitude and longitude of a measurement position for measuring a spatial radiation dose; a regional mesh code is calculated from the latitude and longitude; radiation dose data and date and time for performing measurement are recorded as a set for storage; and a distribution map of a radiation dose of a designated region and a designated period is displayed by displaying a mesh of the current position and a mesh of an unmeasured radiation dose on a map of the designated region and designating the region and a measurement period when measuring the radiation dose.
