Other Radiation Maps
*** RSOE EDIS *** disaster map. This has nuclear as well as other types of emergencies such as environmental contamination and epidemics, as well as geological events.

RadiationNetwork.com USA radiation alert map in CPM (counts per minute).  5-60 CPM is normal BG radiation, 100 CPM is an abnormal alert level.

Online Geiger Counter Nuclear Radiation Detector Map has an iPad/iPhone/iPod app.

CEMP (Community Environmental Monitoring Program) has stations in California, Nevada and Utah. Measurements are in μR/hr (micro-Rads per hour). Divide by 100 to get μS/hr (micro-Sieverts per hour).
* NEW * HAZMAT Situations Map from globalincidentmap.com. (I grabbed this off of RadChick's website Fukushima Facts).

*** Safecast.org ***: Global map with collection of independent as well as government site data from around the world. Safecast.org is featured in CNET.

*** NNI *** a private Japanese citizen put together a radiation map based on data from MEXT (Ministry of Education, Culture, Sports, Science and Technology) and local governments where meters are positioned between 1 and .5 meters. There are 7810 data points as of 6/18/2011. This map is particularly good for visually identifying radiation hot spots.

*** List of nationwide activity concentration *** in Japan, is a not-for-profit site run by earthquake volunteers but based on official government data provided by sources such as MEXT (Ministry of Education, Culture, Sports, Science and Technology) or NISA (Nuclear and Industrial Safety Agency). This site includes links to readings within the various reactors at the Fukushima Daiichi nuclear power plant. Great translation plugin for FireFox: Google Dictionary and Translate. From Tools|Translate entire web pages can be translated, or certain text blocks by holding down ctrl key after having highlighted the text.

*** japan.failedrobot.com ***: Excellent map of 300+ volunteer sites whose data is aggregated via community.pachube.com with the ability to drill down. Readings are in μSv/h.

* NEW (Added 6/8/2013) * Great Lakes Nuclear Hotspots (snagged it from Beyond Nuclear, kudos to them great site)

Radiation Defense Project has a report showing radioactive Iodine and Cesium levels from soil tested in various locations around Japan.

RADIATION READINGS IN THE U.S. provides user submitted readings in blog form.

Geiger Maps Jp maintains a list of radiation maps and other resources.

Nuke Times has radioactive fallout plume maps based on their own modeling methodology which shows a hypothetical graphic of radioactive fallout centered about the various nuclear power plants in the United States.

Map of Radiation Measurements by Greenpeace has measurements taken by members of the Greenpeace environmental activist group. They encourage the public to disseminate and republish their gathered data, some of which can be found here.

USDA Forest Service Los Conchas Wildfire Map is not a radiation level map, but rather a map of the progress of the wildfire which has gotten dangerously close to Los Alamos National Lab (whose grounds serve as storage for a large amount of radioactive waste). You must have Google Earth installed to read the .KML files.

Radiocal (Radiation Awareness Social Network) allows users to contribute their own data if they own a Geiger counter.

National Environmental Radiation Monitoring (Japanese) is a volunteer site run by nuclear science professionals. Reports are in .pdf format.

Wind Map around Fukushima Daiichi Nuclear Power Plant shows data updated every 3 hours.

Geigermap is a collection of independent radiation meters (34 so far) in Japan. Divide the CPM (counts per minute) by 120 to get the μSv/h (micro-Sieverts per hour).

Radiation alteration in Japan after Fukushima accident includes normal levels in addition to current levels for the given day. Note that 1 μGy/h (micro-Gray per hour) is equivalent to 1 μSv/h (micro-Sievert per hour).
Hint: From within the enlarged map, there is a floating "Map Viewer" window on the left side. If you click the "Related Maps" section near the bottom of this floating pane other Japan radiation maps are available.

Wall Street Journal Radiation Levels in Japan interactive map in μSv/h (micro-Sieverts per hour) is updated continuously.

Japan Radiation Maximum by Prefecture has maximum levels which are recorded back since the Fukushima accident and values are measured in nGy/h (nano-Grays per hour). Based on this conversion chart, divide values in the map by 1000 to get the μSv/h (micro-Sieverts per hour), which is the scale used on most meters in Live Streaming Radiation Meters.

EPA Radnet Map View has official US government data.
