The Imaging Survey Meter is being manufactured by Radiation Monitoring
Devices in Watertown,Ma (617-926-1167).  The meter contains two cameras -
one for nuclear imaging and one for video imaging.  The sensor is a
segmented BGO crystal attached to a position-sensitive photomultiplier
tube.  The energy range is between 0.1 and 1.5 MeV gammas.  A second
article says the range is 120 keV to 2.4 MeV.
