<p>PCT No. PCT/JP94/01796 Sec. 371 Date Jun. 20, 1995 Sec. 102(e) Date Jun. 20, 1995 PCT Filed Oct. 26, 1994 PCT Pub. No. WO95/12121 PCT Pub. Date May 4, 1995The invention intends to measure true distribution of a radioactive nuclide in respective parts of a subject. A density of each part of a subject sample is measured by measuring the intensity of ionizing radiation for density measurement from a radioactive nuclide for density measurement, which emits the ionizing radiation to each part of the subject sample in the same amount, through the subject sample interposed midway, the intensity of ionizing radiation emitted from another radioactive nuclide existing in each part of the subject sample is measured, and the amount of another radioactive nuclide in each part of the subject sample is determined by compensating the measured intensity of the ionizing radiation from another radioactive nuclide based on the self-absorptivity of each part of the subject sample corresponding to the density thereof.</p> |
