The Japanese city of Fukushima suffered radioactive fallout following the earthquake that took place off the coast of Japan on 11 March 2011 when the nuclear power plant Fukushima I was wrecked. Two weeks after the accident scientists from FOI arrived in Japan. Björn Sandström and Kenneth Lidström were called in by the Ministry of Foreign Affairs to provide expert support to the Swedish Embassy. The FOI scientists also saw to the taking of samples at locations outside Fukushima. In December FOI was there again.
The visit in December was made together with a delegation from the Swedish Radiation Safety Authority and on this occasion Jonas Boson travelled in place of Björn Sandström.
- We attended a number of meetings with different authorities in Japan and took a lot of new samples,” says Kenneth Lidström.
He and his colleagues are now working on the analysis of the samples that they took on their most recent visit to Japan in December. They also measured the radiation above ground and are comparing these results with the values measured in the ground.
- We also took comprehensive measurements after the Chernobyl disaster but the technology and the methods have developed since then and so it is interesting to see how today’s instruments and methods compare in the measurement of fresh fallout,” says Kenneth Lidström.
- Our research will also enable us to learn more about how the environment looks when radioactive fallout has taken place so recently.
During the time before the disaster in Japan FOI was also assigned the task of taking daily measurements of the radiation from radioactive substances in Sweden.
