     I believe some of the newer units are using neutron sources.  Dr. 
     Anghaie in the Nuclear Engineering Department at the University of 
     Florida may have some good information in this area.  I believe a 
     recent project was detecting landmines from backscattered photons.  I 
     would certainly think the principles are the same.
     
     The phone number to the Nuclear Eng. Dept. is 352-392-1401.

Hello everyone,
     
 I had a question from an employee involving new airport detection 
systems designed to detect explosives.  Apparently these detectors use 
gamma radiation.  The questions put to me were:  How do these detectors 
work?  How do the gamma rays aid in detecting explosives?  Any info on 
these questions would be appreciated!  Thanks.
