Title: Radioactive Nuclides in the Incinerator Ashes of Municipal Solid Wastes before and after the Accident at the Fukushima Nuclear Power Plant
Source: ANALYTICAL SCIENCES, VOL. 29
Date: JANUARY 10, 2013

[...] These results show that 88% of the total radioactive Cs existed in water soluble and ion extractive forms and might be at risk for elution and diffusion with rain and wind. [...]

Following the accident, the Japanese Government established 100000 Bq/kg as the activity concentration limit for radioactive cesium in the incinerator ashes of MSW [municipal solid wastes] that were destined for landfill. [...]

In Japan, most of the incinerator ash of MSW is sent to landfill and these ashes are thus exposed to wind and pH 5.6 rainwater for long periods. As a result, 88% of the total radioactive cesium might be at risk for elution and diffusion due to exposure to rain and wind.
