Google earth map shows ground level radiation in Japan NHK WORLD English

NHK WORLD English:" A Japanese nuclear agency has created a detailed map showing ground radiation levels within 100 kilometers of the Fukushima Daiichi plant.

The Japan Atomic Energy Agency made the map by having a survey team drive through the area in June. The team took readings of aerial radiation once every 10 seconds for several days along routes totaling 17,000 kilometers.

The map uses colors to indicate radiation levels and Google Earth technology to help users pinpoint locations."
