Abstract
Technetium-99 (Tc), produced in the fission of U-235 and Pu-239, has a long half-life (2·1 × 105 year) and has been shown to exhibit a relatively high degree of bioavailability. While Tc can enter the environment from a number of sources [1], the nuclear fuel cycle is the major contributor from the standpoint of point sources. Concentration ratios (CR = μg Tc/g dry wt vegetation per μg Tc/g dry wt soil) for transfer from soils to plants span three orders of magnitude from 1 to 1000 [2–7]. This broad range of CR values presents some difficulty in assessment of dose [8].
