Majia: Radiation Politics

Majia: The Politics of Representation and Radiation Risk

Excerpt:

"Just as the scope of effects from atmospheric testing was narrowed by problematic views of exposure and effects, so also was the scope of effects narrowed from Chernobyl.

So also is the scope of effects narrowed from Fukushima.

The scope of Fukushima effects has been narrowed in many ways, beginning with the the idea that Fukushima Prefecture alone was contaminated. Tokyo, for example, was and remains quite contaminated in areas:
Quote:Ishida M, Yamazaki H (2017) Radioactive contamination in the Tokyo metropolitan area in the early stage of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident and its fluctuation over five years. PLoS ONE 12(11): e0187687. https://doi.org/10.1371/journal.pone.0187687

Abstract: Radioactive contamination in the Tokyo metropolitan area in the immediate aftermath of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident was analyzed via surface soil sampled during a two-month period after the accident. 131I, 134Cs, and 137Cs were detected in these soil samples. The activity and inventory of radioactive material in the eastern part of Tokyo tended to be high. The 134Cs/137Cs activity ratio in soil was 0.978 ± 0.053. The 131I/137Cs ratio fluctuated widely, and was 19.7 ± 9.0 (weighted average 18.71 ± 0.13, n = 14) in the Tokyo metropolitan area. The radioactive plume with high 131I activity spread into the Tokyo metropolitan area and was higher than the weighted average of 6.07 ± 0.04 (n = 26) in other areas. The radiocesium activity and inventory surveyed in soil from a garden in Chiyoda Ward in the center of Tokyo, fell approximately 85% in the four months after the accident, and subsequently tended to rise slightly while fluctuating widely. It is possible that migration and redistribution of radiocesium occurred. The behavior of radiocesium in Tokyo was analyzed via monitoring of radiocesium in sludge incineration ash. The radiocesium activity in the incineration ash was high at wastewater treatment centers that had catchment areas in eastern Tokyo and low at those with catchment areas in western Tokyo.
Fukushima produced substantial fallout across North America.

We found that Fukushima-derived cesium was present in both mushrooms and soil and the soil inventories ranged 2.2-60.9 Bq/m2 for Cs-137 and 16.1-445.8 Bq/m^2 for I131. Additionally, we found that Fukushima-derived cesium inventories in soils were correlated with precipitation gradients. 
Radiation accidents re-occur with alarming regularity. Their impact is always trivialized with claims of no immediate risk:

What risks to the food supply and the environment are posed by chronic exposure to radionuclides in suspended and/or concentrated in air, soil, food, and water?

The mantra of no immediate risk has been deconstructed quite thoroughly, as summarized by Rosie Bertell in her book by No Immediate Danger (excerpted here https://ratical.org/radiation/inetSeries/NID.html).

I’ve been thinking quite a bit about the communication used to represent and govern radiation risk. Most of all, I've been thinking about how its organized to deflect recognition of the scope of hazards."
