Re: Oxford/Canberra LB5100 Y2K problem - Help

determining isotope
efficiency, i.e. decayed values for source activities are greater than
original activities by minus 100 years. The error is apparently in the C++
code or the macros, but in either case can not be fixed in-house, and there
are no patches available from Canberra."

A temporary fix is to manually change the year in the date stored in cell
AA12 (Tennelec software version 2.11) of the efficiency ".xlp" file.  This
is the cell reference for the "current" date in the decay correction
calculation and is the date of the first source count.
