Reuters reports that higher-than-normal rates of certain birth defects plague one Ukrainian region affected by fallout from the 1986 Chernobyl nuclear power reactor explosion. The findings were reported in April’s journal of Pediatrics and counter a 2005 United Nations report by the International Atomic Energy Agency (IAEA) which stated that there was no increase in birth defects. Dr. Wladimir Wertelecki, researcher at the University of Southern Alabama, says that this official conclusion had a “chilling effect” on study of prenatal disease and that these findings show more research is needed into congenital defects, especially in regions of chronic, low-dose radiation.
