About

This article describes a study on thyroid doses in 1,080 children after the 2011 Fukushima nuclear disaster. Researchers reassessed these doses using new methods to measure iodine intake. They found that most children's thyroid doses were below 30 mSv, with similar levels across different age groups and areas. The study suggests ingestion was the main way people took in iodine, not inhalation. It also highlights differences in dose ranges among various towns and cities affected by the disaster. Further research is needed to understand how evacuation behaviors influenced these findings for better future assessments.
