Soil Tests Fukushima
#1
High levels of radioactive material migrating down into soil around Fukushima https://blogs.agu.org/geospace/2017/05/1...fukushima/

Excerpt:

"High levels of radioactive cesium remain in the soil near the Fukushima Daiichi nuclear power plant and these radionuclides have migrated at least 5 centimeters down into the ground at several areas since the nuclear accident five years ago, according to preliminary results of a massive sampling project being presented at the JpGU-AGU joint meeting in Chiba, Japan.

In 2016, a team of more than 170 researchers from the Japanese Geoscience Union and the Japan Society of Nuclear and Radiochemical Sciences conducted a large-scale soil sampling project to determine the contamination status and transition process of radioactive cesium five years after a major earthquake and tsunami caused a nuclear accident at the Fukushima Daiichi plant. 

The team collected soil samples at 105 locations up to 40 kilometers (25 miles) northwest of the Fukushima Daiichi nuclear power plant in the “difficult-to-return” zone where entry is prohibited. The project seeks to understand the chemical and physical forms of radionuclides in the soil and their horizontal and vertical distribution."

"High levels of radioactive cesium remain in the soil.... at least 5 centimeters down into the ground... since the nuclear accident five years ago"
[paraphrased excerpt]

That's about 1 centimeter per year.

5 centimeters is almost 2 inches.

However, over 300 years, which is how long cesium remains Hazardous to life, the cesium will travel downward approximately 10 feet.   Of course some of the top soil over time will turn to dust and blow with the wind and accumulate somewhere else.  

The multitudes of various radioactive contamination Transport Vectors are insidious beyond imagination and will continue for time frames that are difficult to comprehend.

Someday perhaps, we will be asking 'how much' contamination is in that bottle of water or in that bite of food, instead of, is there any contamination in there at all.  Contamination free or very low contamination will be something only humans from prior centuries enjoyed.  Wink  We're pretty much there already.
