Children in Fukushima Prefecture likely received thyroid gland doses of internal radiation, despite earlier government assurances that the levels of such doses were zero, according to an independent study.
The findings run counter to the government’s assertion that they effectively received zero thyroid gland doses.
However, the government has no plans to notify the children’s parents of the latest analysis results, citing their large error margins and the fear of causing anxiety.
“Researchers derived them for scientific purposes,” a government source said. “We have no plan, now or in the future, to notify individuals of their doses.”
The team estimated the lifetime thyroid doses of the 1,080 children at 12 millisieverts on average and 42 millisieverts at the maximum.
Toward the end of March 2011, the Nuclear Safety Commission of Japan advised the Nuclear Emergency Response Headquarters to conduct additional research on children with high doses, but the headquarters rejected the proposal, citing the fear of causing anxiety.
