Ed,
The percent abundance of C-14 in the environment is E-14 according to Clark,
S.P., Jr., ed., 1966, Handbook of Physical Constants, Geological Society of
America Memoir 97, pp 12-17.

Radsafers:
Can someone complete the following table for the natural abundance of
carbon isotopes in the environment and supply the reference.
C12 - 98.89%
C13 - 1.11%
C14 - ?
I have seen a value for C14 of 0.0000000010%. Is this familiar to anyone?
Thanks for the help.
