Fukushima

After a large earthquake followed by a tsunami caused serious damage of the nuclear power plant Fukushima Daiichi in Japan. As a result radioactive substances were released.

Here you can find information about the sequence of the accident as well as the taken and planned countermeasures.

Accident management analysis

Shortly after the accident of Fukushima the Federal Office for Radiation Protection (BFS) calculated the consequences in Germany after an accident like Fukushima in a German Nuclear Power Plant. The results were given in a BfS-Report. Furthermore, BfS calculated more than 5000 case-studies between autumn 2012 and end of 2013. The detailed report was published end of February 2015.

President of Federal Office for Radiation Protection: Course of events of the accident in Fukushima not to be compared with Chernobyl

The president of the Federal Office for Radiation Protection (BfS), Wolfram König, emphasised that the nuclear accident in Japanese Fukushima was not comparable with the disaster of Chernobyl, taking into account all available knowledge. In an interview with the German Press Agency (dpa) in March 2011, König explains what radiation protection measures are being taken in Germany.

Environmental consequences: Radiological situation in Japan

Environmental consequences

The radioactive materials released into the atmosphere as a result of the reactor accident in Fukushima were distributed locally, regionally and globally. The article gives a survey of the radiological situation in Japan. It characterizes the affected areas, assesses the radiation exposure to the people in Japan and gives a survey of the efforts for decontamination of the environment.

BfS report on the accident’s development and causes

One year after the nuclear disaster at Fukushima, the Federal Office for Radiation Protection (BfS) published a report on the development of the accident and its causes. The basic details of the accident and how it progressed are well known. In terms of what happened within the reactors themselves, however, at the time of reporting the experts were dependent on observations which can be made from outside, the knowledge that comes from experience, and reconstruction models using data acquired by other means.
