Radioactivity around Fukushima has decreased by 65% ​​since the accident

Radioactivity levels within an 80-kilometer radius around the Fukushima nuclear plant have fallen by 65 percent since the nuclear disaster in March 2011, Japanese authorities reported today.

The data, compiled by the Nuclear Regulation Authority (NRA) and provided today to Efe, show a significant decrease in radiation in the areas closest to the plant, thanks to the decontamination work carried out in the last five years.

The areas affected by higher radiation levels (over 19 microsieverts per hour), to the northwest of the plant, have been significantly reduced from the first month after the accident until the last measurement, carried out at the beginning of last November.

Radiation has also decreased in areas with levels between 0.1 and 1.9 microsieverts, in towns south of Miyagi and Fukushima prefectures and north of neighboring Ibaraki, according to the NRA report.

The Japanese nuclear regulator collected this data from radiation measurements made by helicopter at a height of one meter above the ground.

After the outbreak of the nuclear crisis caused by the earthquake and tsunami of March 11, 2011, the Japanese government ordered the total or partial evacuation of eight municipalities located at distances of up to 30 kilometers from the nuclear power plant, and since then some 70,000 people have continued if they can return to their homes.

The Fukushima disaster is considered the worst nuclear accident since Chernobyl (Ukraine) in 1986, and its emissions and discharges also seriously affected local fisheries, agriculture and livestock.
