abstract = {DNA-associated Auger-electron emitters (AEE) induce
cellular damage leading to high-LET type cell survival
curves and possess enhanced relative biological
effectiveness. Moreover, DNA dsb induced by
125I-deoxyuridine (125I-UdR) decays are claimed to be very
complex. To elucidate the assumed genotoxic potential,
chromosome aberrations were analyzed in 125I-UdR-exposed
human peripheral blood lymphocytes (PBL).After 18 h labeling
with 125I-UdR the cell cycle distribution is severely
disturbed. Furthermore, $40\%$ of PBL are fully labelled and
$20\%$ show a moderate uptake. Primarily chromatid-type
aberrations are induced. PBL reveal a very broad
dose-dependent response spectrum: equal numbers of cells
have either no aberration, or display a moderate aberration
level. Few cells exhibit a high aberration score (> 10
aberrations). A dose-dependent increase of aberrations is
measured in the range of 0.2 to 2 Gy, followed by a plateau
between 2 and 4.5 Gy. The data indicate that even the lowest
dose of 0.2 Gy leads to a 4.5-fold increase of aberrations
in PBL compared to the controls. Furthermore, a
dose-dependent increase of cell death is observed.125I-UdR
has a very strong genotoxic capacity in human PBL even at
very low doses of about 0.2 Gy. Efficiently labeled cells
display a prolonged cell cycle compared to moderate labeled
cells and cell death contributes substantially to the
desynchronisation of the cell cycle. It can be concluded
that every fourth intracellular 125I decay give rise to a
single chromosome aberration.},
