Half-lives of up to eight days mean that radioactive iodine released in a reactor accident disappears from the environment after about three months.Radionuclides of the elements iodine, tellurium (which decays into radioactive iodine) and caesium were particularly relevant in terms of the radioactive contamination of the environment, as well as that of humans. Outside of Japan, the level of contamination with radioactive material from the Fukushima reactors was low. The radioactive fallout was dispersed locally, regionally and globally over land and sea by the weather (wind and precipitation).Īfter the accident in Fukushima, areas to the north-west of the reactor plant received high levels of contamination, particularly in the prefecture of Fukushima. The reactor accident in Fukushima in 2011 resulted in the release of radioactive material ( radionuclides) into the atmosphere. Radioactive material continues to enter the water used to cool the Fukushima reactors.ĭeposition of caesium-137 in Japan following the Fukushima reactor accident Source: UNSCEAR 2013 Report, Volume I, ANNEX A, Figure B-VIII / reproduced by permission of UNSCEAR.

Almost no foodstuffs in Japan are still contaminated today, with wild boar being one exception.Areas to the north-west of the reactor plant received high levels of contamination, especially in the prefecture of Fukushima.Radioactive fallout was dispersed over land and sea by wind and precipitation.Biological dosimetry following radiation exposure.Comparative tests for passive radon measuring devices.Accredited calibration laboratory.Measurement exercises on the ground.
