The most detailed government maps yet of cesium concentrations and radiation levels stemming from the crisis-stricken Fukushima No. 1 nuclear plant are now available online.
The Ministry of Education, Culture, Sports, Science and Technology site (link below) went live on Oct. 18 with both web-based and PDF versions of the maps, providing not only information by municipality as had been the case previously, but measurements by district.
The maps, intended to help residents who had called for better information on contamination levels between areas of the same municipalities, use soil and air sample data already released. Users are presented with a grid laid over a map of most of eastern Japan. Selecting a square in the grid zooms in on that area, at which point users can choose more detailed maps displaying airborne contamination levels, cesium 134 or 137 levels, or total cesium levels.
