Abstract
The present invention measures the dose distribution of radiation emitted from a measurement region. A dose distribution measuring device comprises a radiation detecting unit and a radiation varying unit disposed between the radiation detecting unit and a measurement region. A dose at the location of the radiation detecting unit is measured by the radiation detecting unit in a state in which the direction from which the radiation, which is to be measured by being varied by the radiation varying unit, is emitted from the measurement region onto the radiation detecting unit, is predetermined. The angular distribution of the radiation dose emitted on the radiation detecting unit from the measurement region is measured by identifying the direction and angle from which the radiation arrives from the measurement region to the radiation detecting unit and calculating the dose of the arriving radiation before varying with the radiation varying unit.
