Fukushima Radioactive Aerosol Dispersal

NOAA’s HYSPLIT model shows clouds of highly radioactive Cesium wafting over the US after Fuku blew sky high. Only one month’s worth shown.

Figure 2. Carl Johnson studied cancer incidence for 1969-1971 among Anglos in three areas downwind of Rocky Flats defined by levels of plutonium contamination in millicuries per square kilometer (mCi/km2) as compared to the uncontaminated control area. See the text above for cancer incidence rate for each area. From Johnson, “Cancer Incidence in an Area Contaminated with Radionuclides Near a Nuclear Installation,” AMBIO, 10, 4, October 1981, page 177 and Table 3 (copyright Royal Swedish Academy of Sciences, reprinted by permission of Allen Press Publishing Services).

Fires in 1957 and 1968 sent an unknown amount of highly radioactive material over the Denver area. Johnson found higher cancer rates the closer he got to Rocky Flats.

Radionuclide contamination in Fukushima and adjacent prefectures

The outside annual radiation dose due to the radionuclides from the Fukushima accident is estimated to be 10 mSv in Naka-Dori, 40 mSv in Iitate, 0.2 mSv in the region between northern Ibaraki and eastern Saitama, and 2 mSv in southern Ibaraki and northern Chiba prefectures (note that the present estimate does not include the doses from short-lived radionuclides). No internal dose contribution is assumed in these estimations.
