The latest joint US and Japan survey shows extremely high levels of nuclear radioactive contamination, with radiation levels higher than Chernobyl evacuation limits, now span over 800 kilometers in Japan.<\/p>\n

Meanwhile US Media outlets continue to ignore the situation and run stories that the situation is under control.<\/p>\n

Radiation-contaminated area spans 800 square km, new map shows<\/h3>\n

By Hisae Sato and Fumikazu Asai
\n12 May 2011<\/p>\n

The total area contaminated with radiation from the Fukushima No. 1 nuclear power plant is estimated at about 800 square kilometers, or about 40 percent the size of Tokyo, according to a radiation map created by the science ministry and U.S. Department of Energy<\/strong>.<\/p>\n

The report uses the same level of contamination (555,000 becquerels or higher of cesium-137) that was used to issue compulsory evacuation orders in the Chernobyl nuclear accident in 1986. \u2026<\/strong><\/p>\n

The report\u2019s radiation levels were determined in April by measuring, from about 150-700 meters above ground, levels of accumulated radiation on the ground. The areas measured were divided into 1- to 2-square-kilometer zones.<\/p>\n

According to the map, about 800 square kilometers are contaminated with accumulated cesium-137 of 600,000 becquerels or higher per square meter.<\/strong> The substance has a half-life of about 30 years.<\/p>\n

Late afternoon on Monday, March 14, 2011, the Department of Energy and the National Nuclear Security Administration deployed 33 people and more than 17,200 pounds of equipment \u2013 including Consequence Management Response Teams and NNSA Aerial Measuring Systems \u2013 to Japan in response to the recent earthquake and tsunami.<\/p>\n

This video illustrates how the team managing the Aerial Measuring Systems accomplish their mission. It comes from a training mission in Nevada \u2014 it is not footage from Japan.<\/p>\n<\/blockquote>\n

The Situation in Japan (Updated 05\/13\/11)<\/h1>\n

As the situation in Japan continues to evolve, we want to keep you abreast of the latest information on the assistance and expertise we\u2019re providing to the Japanese response and recovery efforts. Please take note of the dates attached to each piece of information, as this is a very fluid situation that is continually evolving.<\/p>\n\n

In March, the U.S. Department of Energy released data recorded from its Aerial Measuring System as well as ground detectors deployed along with its Consequence Management Response Teams. Today, the Department provided the following update on the information gathered by the AMS. This is the second round of data that was collected and analyzed jointly with the Government of Japan\u2019s Ministry of Education, Culture, Sports, Science and Technology (MEXT).
