How Sunflowers Absorb Radioactive Elements - Sunflowers were planted after the Fukushima disaster because they can absorb certain radioactive elements like cesium-137 and strontium-90 from contaminated soil, a process known as phytoremediation. These elements mimic nutrients, allowing the plant to take them in and store them within its tissues. While this can help reduce contamination levels, the process is slow and requires the plants to be safely disposed of as radioactive waste afterward. #vi
