Japan Radiation Map Roundup

If you want to know what's going on, ask the nerds. As fears swelled over radiation from Japan's battered Fukushima Daiichi nuclear power plant in the days after the 11 March quake, computer-savvy individuals around the globe had an immediate reaction: show people the data. Within days, individuals began tracking down and using the data to create interactive maps and graphs of radiation levels in Japan. Here are some that have stood out as especially useful. Their sources include government monitoring stations and Geiger counters duct-taped to the balconies of Tokyo apartments, and vary in completeness and in how frequently they're updated. Neither Science nor the creators guarantee these maps' accuracy; they are meant to supplement, not replace, official formats of releasing data. These maps are works in progress, and new ones are coming online every day.
