Government figures show airborne radiation levels in the vicinity of the Fukushima No. 1 nuclear plant fell by about 40 percent over the course of a year, reflecting natural decay and dispersal by wind and rain. [...]
Ministry officials attributed the decline in roughly equal measure to decay, and to wind blowing radioactive material elsewhere and rain sluicing it out to sea.
“Typhoons hit in June and later,” a ministry official said. “They may have helped spread the radioactive substances.” [...]
High-sensitivity sensors fitted to helicopters were used to calculate radiation levels at a height of 1 meter above the ground [...]
The first three surveys were conducted with different analysis methods, so it remains difficult to compare readings across the entire period since the March 11, 2011 disaster, the ministry officials said.
