Chris Busby theecologist.org A new study finds that radioactive Iodine from Fukushima has caused a significant increase in hypothyroidism among babies in California, 5,000 miles across the Pacific Ocean. The Fukushima catastrophe has been dismissed as a potential cause of health effects even in Japan, let alone as far away as California. A new study of the effects of tiny quantities of radioactive fallout from Fukushima on the health of babies born in California shows a significant excess of hypothyroidism caused by the radioactive contamination travelling 5,000 miles across the Pacific. The article will be published next week in the peer-reviewed journal Open Journal of Pediatrics. Congenital hypothyroidism is a rare but serious condition normally affecting about one child in 2,000, and one that demands clinical intervention - the growth of children suffering from the condition is affected if they are left untreated. All babies born in California are monitored at birth for Thyroid Stimulating Hormone (TSH) levels in blood, since high levels indicate hypothyroidism. Joe Mangano and Janette Sherman of the Radiation and Public Health Project in New York, and Christopher Busby, guest researcher at Jacobs University, Bremen, examined congenital hypothyroidism (CH) rates in newborns using data obtained from the State of California over the period of the Fukushima explosions. Their results are published in their paper Changes in confirmed plus borderline cases of congenital hypothyroidism in California as a function of environmental fallout from the Fukushima nuclear meltdown. The researchers compared data for babies exposed to radioactive Iodine-131 and born between March 17th and Dec 31st 2011 with unexposed babies born in 2011 before the exposures plus those born in 2012. Confirmed cases of hypothyroidism, defined as those with TSH level greater than 29 units increased by 21% in the group of babies that were exposed to excess radioactive Iodine in the womb [*]. The same group of children had a 27% increase in 'borderline cases' [**]. Contrary to many reports, the explosion of the reactors and spent fuel pools at Fukushima produced levels of radioactive contamination which were comparable with the Chernobyl releases in 1986. Using estimates made by the Norwegian Air Laboratory it is possible to estimate that more than 250PBq (200 x 1015) Bq of Iodine-131 (half life 8 days) were released at Fukushima. This is also predicted by comparing the Caesium-137 estimates with I-131 releases from Chernobyl, quantities which caused the thyroid cancer epidemic in Byelarus, the Ukraine and parts of the Russian Republic. More on this later. At Fukushima, the winds generally blew the radioactive iodine and other volatile radionuclides out to sea, to the Pacific Ocean. The journey 5,000 miles to the West Coast of the USA leaves a lot of time for dispersal and dilution. Nevertheless, small amounts of I-131 were measured in milk causing widespread concern. to read more click here: theecologist.org
