A Crowdsourced Japan Radiation Spreadsheet
The Japan Ministry of Education, Culture, Sports, Science and Technology (MEXT) publishes real time radiation data on their website, but there are two issues:
- The site is under heavy load
- The historic values aren’t available
So I created a Google Docs Spreadsheet to collect the real time data and store the values for later use.
Please, if you can, contribute to the document. Copy the real time values from the original source to the spreadsheet.
And, more important, please spread the word.

Update 2011-03-16 0:03 UTC: Data from the bousai website is now gathered automatically and can be downloaded as CSV.
Update 2011-03-16 20:07 UTC: The original spreadsheet, open to the public for editing, is still available. There is now a Google Docs Spreadsheet with prefecture max values derived from the CSV download mentioned above. That file is read-only for the public. The URL is http://goo.gl/RMuNt.
Update 2011-03-17 23:40: Information about the location of sensor stations are now available in a Google Doc under http://goo.gl/iDo0N.
Update 2011-03-19 10:34 UTC: Updated information is available in a new blog post. In brief: The data collection I started manually with the spreadsheet this post was about is now done automatically and available for download. However, people still work with the spreadsheet and have entered additional data sources.
Update 2011-03-22 14:18 UTC: Someone changed the settings for the original crowdsourced spreadsheet so that only a few people can edit now. I decided to leave it that way and updated the meta-information in the sheet so that people don’t waste their time with manually entering stuff, fighting trolls or looking at incomplete data.
