<p>A phantom device for measuring a radiation quantity is provided to check distribution of does around a target point by measuring the radiation quantity with a plurality of thermoluminescence dosimeters arranged three-dimensionally. In a phantom device for measuring a radiation quantity, more than one slab has a plate shape having a predetermined thickness to be permeated by radiation. The slab has a plurality of thermoluminescence dosimeters at one or both sides. The thermoluminescence dosimeter is reactive to the radiation. A phantom(32) has a frame to support the slab for the radiation to pass through the slab in a thickness direction.</p> |
