I have spoken with my engineer, Bill Zimmer.  He needs more information to
even guess at the tritium efficiency.  He needs to know the source.  What
is the detector configuration and window?  What is the geometry?  It can be
done when using a smear counter such as the Xetex Abacus with plastic
scintillation detector.  A thin layer of scintillator is optically coulpled
to an acrylic light pipe.
