Tritium, the heaviest and only radioactive isotope of hydrogen, is
increasing in importance in energy and environmental considerations.
This nuclide is widely distributed throughout man's environment
because of its ubiquitous form as tritiated water and its persistence in
the environment. This report considers and evaluates the available
information on tritium in terms of its physical properties, production
sources, physical transport, biological behavior, projected future production,
waste management, and the long-term dose implications of
tritium in the environment....
In 1968 the NCRP Board of Directors, in an expansion of its internal
emitter effort, assigned to Scientific Committee 24 the task of examining
tritiated thymidine to determine whether the values for pennissible
body burdens and concentrations of tritium as tritiated water
given in NCRP Report No. 22 would be applicable. As the Committee
studied the problem, they decided it would be appropriate to examine
all radionuclides and additional compounds that have the potential for
incorporation into genetic material....
