The outcome was a CSV file updated every 10 minutes
and including data for the last hour.

Table 6.2. An example of the eight first values in the spreadsheet generated
automatically on Marian Steinbach's website on September 24, 2012 19

The final file includes the station number, the date and
time, the radiation value in nanoGray/hour (SA) and the
precipitation in millimeters (RA) 20 . Another file containing
all the values produced since March 1, 2011 21

up to the

moment of the download is also shown.

Due to the challenges concerning format explained above,
some of the sources did not allow automatic data collection,
and hence required the manual insertion of data on the map.
This was a problem among others for the Fukushima and
Miyagi districts as mentioned below:
