Mercuric Iodide X-Ray Camera

A prototype x-ray camera utilizing a 1.5-by 1.5-inch, 1024-element, thin mercuric iodide detector array has been tested and evaluated. The microprocessor-based camera is portable and operates at room temperature (Figure 1). Events can be localized within 1-2 mm at energies below 60 keV and within 5-6 mm at energies on the order of 600 keV.
