Can growing sunflowers help draw radioactive particles out of the soil in contaminated areas of Fukushima prefecture? Swedish newspaper DN thinks so, and had this lovely photo by Kerstin Joensson, which I thought was too good to not share with you.
Also, it had a link to an article in The Telegraph that claims there have been similar projects in Chernobyl.
Scientists believe that sunflowers at their full height can absorb large quantities of radioactive caesium, resulting in their growing presence across the Fukushima landscape in order to help decontaminate soil.
The Telegraph: Sunflowers heal soil across nuclear-hit Fukushima
I'd like to see the scientific reports that are behind this. We know that the levels of Caesium isotopes are extremely high in certain areas in Fukushima, from independent testing. It may take a long time before soil with such levels can be used for farming food again. But anyway, the flowers are pretty and bright!
