9km south of Fukushima Daiichi Nuclear power Plant

Once a busy shopping area, now abandoned and derelict.

There were numerous radiation micro hotspots here, particularly around drains and gutters where radionuclides typically accumulate, transported there by rain, melted snow and street-cleaning. The highest level of radioactivity I found was in some mud in a drain at the edge of a forecourt, measuring 11.8μSv/h (microsieverts per hour) ~ 103 millisieverts per year.
