Operation Himawari

Japanese researchers are planning a project to plant as much sunflowers as possible, which will remove redioactive cesium from contaminated soil around the Fukushima Daiichi nuclear power plant.



It is known that some plants absorb radioactive substances in soil, and especially sunflowers have powerful absorbing ability.

They can absorb more than 95% of radioactive materials in only 20 days.




The following illustration is helpful to understand that operation.

Researchers believe that suflowers will be a symbol of recovery in the areas affected by the nuvlear crisis.
