Conclusion IIf there is natural radiation background in Japan 0,1 MICRO
Sv/h that is right the mass media statement that Fukushima City had almost 200 times higher radiation on March 15 than Japanese background.
If you go to a CT (Computed Tomography) diagnistic examination you will obtain as the dose as at the Fukushima Nuclear Power Plant front-gate after 5 hours exposition or in Fukushima City after 31 days exposition (radiation related to March 15).
In Kotka, Finland my shoulder will be dislocated, after that I was sick with pneumonia and so I had to visit 5 times X-ray (RTG) diagnostic centre and so I approximatelly obtained as the dose as in Iwaki City after 30 days exposition (related to March 15).
