Colorado State University employes the use of the Tennelec LB5100
Alpha-Beta-Gamma Counter. It has a gas flow proportional counter as well as a
NaI.  We find it very useful for our wipe tests and laboratory evaluations on
campus.  Of course, the low energy betas and gammas have reduced efficiency,
but as a whole, we rely on it a great deal.  MDA's and Action levels can also
be set within the system.  Efficiencies for a variety of radionuclides can be
determined and stored in memory as well. If you have the money, I would
recommend it.
