Catastrophe Pie Charts
The July 26 – August 12 accident emission rate estimate of 200 million Bq/hr of gross radiocesium can be contrasted with the radiocesium soil contamination survey, also released on August 29th. Gross radiocesium levels approaching 30 million Bq/meter squared in the town of Okuma provide a startling juxtaposition with the current accident emissions rate estimate. No similar levels of Chernobyl-derived radiocesium contamination were noted in 2001 when Chernobyl Fallout Data 1986 – 2001 was published. Much of this data is reproduced in Section 8 of the Davistown Museum’s Nuclear Information Handbook (http://www.davistownmuseum.org/publications/volume62.html). It should be noted that the Fukushima Daiichi accident source term (release inventory), probably significantly larger than the Chernobyl source term, is only one among thousands of slices of the Anthropogenic Radioactivity Pie Chart. This pie chart includes thousands of point sources ranging from weapons testing cumulative fallout (+/- 3500 Bq/square meter Cs-137) to Savannah River, the Russian Arctic, etc. The Anthropogenic Radioactivity Pie Chart is, in turn, only one slice of the Biocatastrophe Pie Chart.

For a survey of the ongoing impact of the human ecology soap opera, blog readers are invited to visit amazon.com and buy a Kindle version of the three volume Phenomenology of Biocatastrophe series and take it to the beach. Both our Fukushima Daiichi Nuclear Information Handbook and our 5 volume survey of Hand Tools in History are also available on amazon.com.
