Battelle review cuts iodine release estimates
A new study has concluded that radioactive iodine released from the Energy Department's Hanford complex in the 1940s and 1950s was more widely dispersed than previously believed, prompting researchers to lower their estimates of likely radiation doses to those living near the nuclear weapons facility. However, despite the lowered doses, the study found those living closest to Hanford still suffered radiation doses to the thyroid gland more than 1,000 times higher than those resulting from natural radiation in the environment. Researchers said the highest doses probably were received by infants and children who drank milk from cows that grazed in local pastures heavily contaminated by the Hanford releases. Milk from cows was found to be the biggest pathway for contamination by iodine-131, the contaminate estimated to account for 98 percent of the radioactivity released into the air at Hanford during its plutonium production period from 1944-1951.
