        I need information on materials suitable for use as x-ray detectors. 
I am looking for the following qualities: a scintillation decay time of <50ns,
a high density (stopping distance of <.5 inch, the scintillator should be 
fairly planar), and useful at low energies (20-100keV). The literature I am 
familiar with mostly discusses materials suitable for synchrotron applications,
I am looking for things more useful in medical imaging.
        If you know of any relevant papers, I would appreciate it if you could
send me the reference or a reprint. I can be reached at
