Fukushima: 9 Months later

With regards to airborne radiation and ground measurement, here is the reading at the NaI detector at KEK in Tsukuba showing a steady decline over the past nine months. This was expected as the source became under  control over time.

I note that the mapping situation has readily improved over the past few months: see for instance this ground measurement map at Fukushima Dai-Chi plant and in the region surrounding it (via the Japan Radiation Map)
