DETECTOR SYSTEM FOR DIRECT INTERNAL DOSIMETRY IN HUMAN BEINGS.

摘要

In a detector system for direct internal dosimetry of persons which comprises at least three gamma radiation detectors mounted on a support structure including a seat-like structure on which a person is supported in a seated position, the support structure has a first one of the detectors mounted thereon such that its central axis is directed toward the lungs of the person, a second detector mounted into the seat-like structure such that its central axis is directed upwardly toward the center of the digestive tract and a third detector arranged so that it is disposed above and its unshielded face is directed downwardly toward the legs of the person being checked for determining gamma ray emission from the whole body of said person.
