HETEROGENEOUS PHANTOM FOR MEASURING RADIATION DOSAGE USING PLURAL PLATE MEMBERS HAVING DENSITY CORRESPONDING TO DENSITY OF A PREDETERMINED TISSUE OF A HUMAN BODY

PURPOSE: A heterogeneous phantom for measuring a radiation dosage is provided to precisely predict a radiation dosage in a human body by using a plurality of plate members having density corresponding to density of a predetermined tissue of the human body. CONSTITUTION: A heterogeneous phantom for measuring radiation dosage includes a plate stacker(31) having a predetermined thickness. The plate stacker(31) includes a plurality of stacked plates and allows a radiation irradiated from an external device to pass. The plate stacker(31) has electronic density identical to tissue density of a predetermined portion of the human body. A measuring device is installed at the plate stacker(31) in order to measure the energy level of the radiation transmitted through a unit plate. Frames(23,25) are provided to support the plate stacker(31).
