Περίληψη:
THERE has been no documented increase in childhood leukaemia following
the Chernobyl accident. However, different forms of childhood leukaemia
may not be equally susceptible to radiation carcinogenesis. Infant
leukaemia is a distinct form associated with a specific genetic
abnormality. Outside the former Soviet Union, contamination resulting
from the Chernobyl accident has been highest in Greece and Austria and
high also in the Scandinavian countries(1-4). All childhood leukaemia
cases diagnosed throughout Greece since 1 January 1980 have been
recorded. Here we report that infants exposed in utero to ionizing
radiation from the Chernobyl accident had 2.6 limes the incidence of
leukaemia compared to unexposed children (95% confidence interval, 1.4
to 5.1; P approximate to 0.003), and those born to mothers residing in
regions with high radioactive fallout were at higher risk of developing
infant leukaemia. No significant difference in leukaemia incidence was
found among children aged 12 to 47 months. Preconceptional irradiation
had no demonstrable effect on leukaemia risk at any of the studied age
groups.
