FOIA’s Related to Radiation Levels from Fukushima Daiichi

Our FOIA archives feature collected and sorted FOIA documents, and are sub-categorized by event, topic, importance, and type. Email chains are extracted and published according to date. Press releases are archived by date of publication. Presentation materials and pdfs are summarized and displayed in whole. Each post is titled with the date of transmission of that particular FOIA combined with the subject of the message.
