Abstract
Discriminating radioactive nuclides of a gamma ray source and nondestructively measuring an image concentration and spatial distribution of a gamma ray by radioactive nuclides. A visualizing apparatus having a containerincluding a gamma ray source; a gamma ray detectoraround the containerwhich detects gamma rays through a collimator; a gamma ray detection signal processing devicewhich processes a gamma ray detection signal measuring energy and counted value thereof; an energy discrimination processing devicewhich performs discrimination and intensity analysis of radioactive nuclides by performing spectrum analysis of gamma ray energy and intensity measured for each unit time or position; an imaging calculation processing devicewhich forms images of concentration and space distribution of the gamma ray source for each discriminated radioactive nuclide; and an image display devicewhich performs visual display based on a result of the calculation processing.
