Radiation Readings (Not Live Updated)

We are gradually adding environmental radiation readings taken since the beginning of the disaster to build a clear picture of the contamination over time. Please check back frequently as this will be an ongoing project. Please note that some of the government-sponsored monitoring has been found to read artificially low for various reasons such as the height of monitoring posts or aggressive decontamination near monitoring stations.

Readings In Japan:

MEXT (Japan Ministry of Education) Radiation monitoring stations. Please note that these readings are for the actual location where the monitor is located, some monitors are atop multiple story buildings. The “adjusted to 1meter off the ground” reading is usually buried in fine print and is the important reading. MEXT has also been found to be decontaminating around monitoring stations or setting them on top of metal plates to make the readings artificially lower. So these readings are artificially lower than the reality at that location.  http://radioactivity.mext.go.jp/map/ja/area2.html Dead link, page reverts to NRA’s data page https://radioactivity.nsr.go.jp/ja/
