[Last updated: Dec 5, 2012] There are several possibilities:
- ! –> A very large number of monitors across Japan, graphing radiation measurement (in the SI radiation dose unit µSv/h (‘microSievert per hour’ – see Radiation Units for conversion info) in near-real-time: http://ma-04x.net/all.html This image (below) is a screenshot I took on Dec 5, 2012 (already Dec 6, 2012 in Japan), showing clearly that radioactive particles continue to be blown around and/or released into the atmosphere:
It’s too bad the graphs don’t show the specific locations in English as well, but perhaps the following is helpful: the parent page (http://ma-04x.net/) has this following menu (with my ‘Google Translator‘ translations added):
全国 (福島県は相双地域のみ) Japan (Fukushima Prefecture is a bi-phase region only)
- 北海道・東北 (福島県は相双地域のみ) Hokkaido and Tohoku (Fukushima is bi-phase region only)
- 関東・甲信 Kanto-Koshin
- 北陸・東海 Tokai-Hokuriku
- 近畿・中国 Kinki, China
- 四国・九州 Shikoku and Kyushu
- 福島県全域 Throughout Fukushima Prefecture

> Word of CAUTION regarding the Japanese official monitoring posts: ‘Levels nearby much higher than some monitoring posts indicate‘. Also keep in mind that comparing dose rates is not necessarily a dependable way to gauge dangers from fallout. See Caution with links at ‘Health Exposure Effects’!
- !–> For Tokyo, there are (at least) these three live monitors with graphs and important weather information:

BELOW: Most of the links listed below still work, but where they don’t, I’m leaving them up as a tribute to (and archive of) how this blog got started. — I put this list together within days after the Fukushima-Daiichi NPP disaster, and improved upon it for many weeks. It was really good in March-April 2011. Unfortunately some sites have reduced, rather than improved, their access since. :-/ I’m leaving it as-was for now. See the newer above link(s), and the Radioactivity tab for more.] /

- –> SPEEDI – System for Prediction of Environmental Emergency Dose Information, is the extensive near-real-time monitoring network of the ‘Japan Nuclear Safety Division’. See clusters of monitoring areas in this image (image is a screen-shot taken March 18, 2011); for Current Measurements, CLICK ON THE IMAGE below, and then select a prefecture to get the most recent data from that prefecture’s many monitoring stations:
Note: These SPEEDI reports are in nGy/hr or ‘nanoGray per hour‘. See the Radiation Units page for a better understanding of the different units. The nanoGray allows for differentiation between different absorbtion rates for different species. Conversion for humans is easy: 1 nGy/hr ≈ 0.001 µSv/hr. On 3/17/2011, a reading of 700 nGy/h thus corresponded with an unusual 0.7 µSv/hr. See the Radiation Exposure Effects page to help put the measurements into context.
- –> Independent monitor in Hino City, Tokyo: streaming near-real-time Geiger Counter data, reporting in CPM (in this case: 12 CPM≈ 0.1 µSv/hr), plotted on a nice graph. For additional questions, see their FAQ page (English below Japanese). Graph is for reference (with normal levels in the 10 – 25 CPM range (≈ 0.08 – 0.21 µSv)
Click on the Reference Graph below (showing normal radiation measurements, Dec 5, 2010) to access the current measurements:

- NAZ – Nationale Alarmzentrale (based in Switserland) Concise overviews of the radiation measurements in Japan. The map right below [an outdated static screen shot] serves as a reference for measurements on March 19, 2011. Click on the map(right below) for the most recent measurements reported by NAZ, or check for Updates from the NAZ regarding the situation in Japan. (If you don’t speak German or Japanese, try copy-pasting the text into Google Translate, or look for a pdf-document like “Radioaktivitätsmesswerte Japan vom 19.03.0900 (pdf)” with the latest date and time. It may not be best for near-real-time monitoring, it does give a clear overview of the day’s unfolding:
- Twitter #Gwatcherver2: over a dozen Twitter feeds with CPM radiation measurements feeds, brought together and graphed. If need be, Google Translate can help to get the gist of the Japanese text. Check the tweeted-in Data Tables of CPMsfor more details.
- Additional information can be found on some Twitter feeds. Examples (if any are outdated: search keywords for new/recent):
- TepcoDisaster# (operators of the troubled reactors)
- The Japan Times
- The Japan Daily
- etc… (Check also AP, Reuters, etc…)
My heart goes out to the people of Japan suffering under the triple blow of the effects of the earthquake and tsunami, as well as the social, economic and health effects of the ongoing Fukushima Nuclear Disaster.
