    摘要: Radiation transmission intensity information obtained from a radiation source (41) of two different energy levels or energy bands is used to perform an energy subtraction calculation and to quantify the constituent substances of the object (45) being analyzed in a single operation using a single subtraction calculation equation.
    When three substances (11-13;21-23;31-33) are overlapping in the direction of radiation transmission, using the transmission intensity information from a radiation source with only two energy levels, the effect of one substance is eliminated while identifying and quantifying the other two by applying an energy subtraction calculation process. Based on the calculated result for the area containing the first and second substances, the density of the third substance can be obtained.

    摘要: Disclosed are a radiation detector and a method of manufacturing the same. The radiation detector includes a radiation screening member (4) for cutting off radiation (1) incident upon the marginal portions of the radiation incident surface of a semi-­conductor radiation sensor or a semiconductor radiation sensor array (2) for outputting pulses in correspondence with radiation phontons, as well as upon the boundary portions between adjacent sensors (7a). In order to manufacture such a radiation detector, leads (3a) are provided by the wire bonding, soldering or bump contact­ing on the radiation screening member, and at least part of the radiation screening member (4) is then fitted to the semiconductor radiation sensor or the semiconductor radiation sensor array (2) so as to make it electrically connected to the electrodes (3) of the semiconductor radiation sensor or the semiconductor radiation sensor array (2).
