JAEA "finally" tracks contamination in immediate vicinity of Fukushima plant.. like they didn't know.......

The Japan Atomic Energy Agency used an unmanned helicopter to crack a missing piece of the puzzle regarding radiation contamination close to the wrecked Fukushima No. 1 nuclear power plant.
It has finally come up with the first detailed study of radiation levels within a 3-kilometer radius of the center of the plant. The zone has been inaccessible to scientists because of the three reactor meltdowns triggered by the 2011 earthquake and tsunami disaster.
The JAEA measured radiation levels within 3 km of the stricken plant between August and October last year, and detected readings of more than 19 microsieverts per hour south and west of the nuclear plant.
The government-affiliated research body said radiation levels remained relatively high northwest of the facility as well.
It also investigated radiation levels above ground within an 80-km radius of the plant, and found that the extent of contamination has fallen 36 percent from a previous survey.
