* There would be another cost, of course—combusted carbon, the focus of this book. According to the Ministry of the Environment, one of three methods for “volume reduction of contaminated soil” was “heating processing,” by “using rotating heater and reaction accelerator together to separate cesium from soil[.] [A]lmost all cesium is collected by a bag filter. Decontamination rate is 99.8–99.9%,” which sounded splendid, although maybe less so from the standpoint of “volume reduction” since “the volume of purified soil is doubled because reaction accelerator is needed to add the same amount of the soil.” Now for the price: “It costs about 200,000 yen/t[on] (400 t/day, for 10 years running)” [my italics]. That would be an impressive amount of CO2—to say nothing of the energy required to run the reaction accelerator for that decade.
