DETERMINING 14C CONTENT IN DIFFERENT HUMAN TISSUES

English: Atmospheric 14 CO 2 in the second half of the 20 th century. The figure shows the 14 C / 12 C ratio relative to the natural level in the atmospheric CO 2 as a function of time in the second half of the 20th century.. The plot was generated with gnuplot from data of atmospheric radiocarbon in Wellington, New Zealand 1954AD to 1993AD and at the Vermuntsee, Austria 1959AD to 1983AD.
