ABSTRACT:
An ionizing radiation imaging detector, for use with a ionizing radiation beam source comprising a pixellated conversion-detection unit, and a substrate supporting the conversion-detection unit. The substrate includes one or more elements having atomic numbers greater than 22, the elements having a total concentration in the substrate of greater than about 1 mole percent relative to the total number of moles of elements having atomic numbers of 22 or less. The substrate has a dimensionless absorption exponent of less than 0.5 for gamma ray emission of Am.sup.241 at about 60 keV;
