ABSTRACT

Various reports indicate that the incidence of congenital hypothyroidism
 is increasing in developed nations, and that improved detection and more
inclusive criteria for the disease do not explain this trend entirely. One risk
 factor documented in numerous studies is exposure to radioactive iodine
found in nuclear weapons test fallout and nuclear reactor emissions. Large
amounts of fallout disseminated worldwide from the meltdowns in four
reactors at the Fukushima-Dai-ichi plant in Japan beginning March 11, 2011
 included radioiodine isotopes. Just days after the meltdowns, I-131
concentrations in US precipitation was measured up to 211 times above
normal. Highest levels of I-131 and airborne gross beta were documented
 in the five US States on the Pacific Ocean. The number of congenital
hypothyroid cases in these five states from March 17-December 31, 2011
was 16% greater than for the same period in 2010, compared to a 3%
decline in 36 other US States (p < 0.03). The greatest divergence in these
 two groups (+28%) occurred in the period March 17- June 30 (p < 0.04).
Further analysis, in the US and in other nations, is needed to better
understand any association between iodine exposure from Fukushima-
Dai-ichi and congenital hypothyroidism risk.
