を特徴とする放射線断層測定装置。 Radiation is irradiated from multiple directions from a radiation source on the measurement target cross section of the object to be inspected, and the transmitted data is detected and collected with spatial resolution, and an image is reconstructed from the collected data to create an image of the measurement parabolic cross section. In the apparatus for obtaining radiation, a radioactive isotope is used as the radiation source, and the radioactive isotope is placed in a radiation source container formed with a plurality of radiation emitting holes extending in the radiation irradiation direction and forming a pencil game at a predetermined pitch. A radiation tomography measuring device characterized in that it is housed and installed and configured to emit parallel pencil beam radiation.
