get on tritium releases is plotted along the top of Fig. 1] including releases
from Savannah River, Handord, Los Alamos and Livermore,
We believe
the data to be complete although one must realize thai complete accounta~
bility would be very difficult to achieve. For example, in the case of Los
Alamos releases in 1955/56 the sum of the monthly releases does not agree
with the figure of 114,000 curies listed as total releases, We believe,
therefore, that the release information tabulated along top of Fig. 7is
probably in error on the low side and represents only those releases which
are actually known,
I hope this may furnish background data for our discussion ofthis
problem.
This letter is classified TOP SECRET RESTRICTED DATA because
it reveals the fact that AEC production activities are releasing large
amounts of tritium.
Sincerely,
