Please note that his spreadsheet is no longer needed to track radiation data. Meanwhile we found ways to get that same data automatically from the source website. Read info below.

That's why it's not necessary to update that sheet any longer.

Purpose:As the sheet was opened, the purpose was to collect real-time radiation data from Japanese administration for later use, e.g. time-series analysis. This is now obsolete, since there are automnated ways accessible to everyone on the web.

UnitsAll units measured in nGy/h (nano Grays per hour). Conversion between Gy and Sv (Sievert) is not simple, since Sievert is a measure for biological harm of radiation and values different kinds of radiation differently. Some source use 1Gy = 0.8 Sieverts(Sv), others use 1 Gy = 1 Sv.

Note that there is now an automatic data collection (starting at 10:55 UTC on March 15) with CSV downloads available at -->http://goo.gl/qKEOd
