Annotated Photos of Fukushima | by Dave Lochbaum | nuclear power | nuclear power safety | Japan nuclear |
A set of very high-resolution photographs of the Fukushima Dai-Ichi nuclear plant have been posted on the web by cryptome.org. I’ve annotated some of those pictures below to help people know what they are seeing in those photos.
