  • Procedure to measure the radioactivity of radioactive material enclosed in a container
    Patent number: 6407394
    Abstract: A procedure having the steps of: weighing a known volume container (4) in order to determine the average density of its content; positioning the container (4) upon a support (1); positioning on respective supports (5) two &ggr; ray detectors (6) set symmetrically to the container; causing vertical movement (F2) of the container, so that its main longitudinal axis coincides with the axis (I—I) connecting the two detectors (6); causing movement (F1) of the two detectors upon their respective supports in order to stop them in a first tentative position; causing movement (F1) of the two detectors in order to stop them in a second symmetrical position that proves to be suited to providing countings of the radiations that are an optimum; measuring the &ggr; radiation and calculating the geometric mean of the counting ratios of the two detectors, such a geometric mean being linked to the intensity (I) of the corresponding &ggr; radiation by a formula (1-2) from which the radiation intensity is calculated.
