What Have Sunflowers Got To Do With Nuclear Disasters?

- Sunflowers are the international symbol for nuclear disarmament. You will most likely find sunflowers around areas where nuclear disasters have occurred in the past. Following the 1986 meltdown at the Chernobyl Power Plant in Ukraine, which released over 100 radioactive elements into the environment, sunflowers were planted in droves to extract the radioactive isotopes from the fallout-impacted sites. This approach is based on the principle of phytoremediation, which employs the use of plants to cleanse the environment.
The Chernobyl sunflower project was born in 1994 when a New Jersey-based company planted sunflowers on a floating raft with the intention to absorb radioactive isotopes from the water. It was observed that the plants selectively absorbed radio-cesium (137Cs) and radio-strontium (90Sr) from the water, and results indicated that about 95% of the radio-nuclides had been cleared out in a span of only ten days. In this video, we explore this magical ability of sunflowers in more detail.

That's why we need to protect nature and not exploit it for money
Thank you again for always dropping knowledge! Please keep them coming.
Amazing content!! Learnt it new 😀😀
Awesome! Thank you!
🌻🌻🌻🌻🌻 Totally going to geek out learning more about sunflowers today. 🌻🌻🌻🌻🌻
Wonderful!
Mantap
Çok teşekkürler. (Thanks.)
You are welcome :)
End results is again radiactive material.
If you can find radioactive material on earth, does it mean that radioactivity as a naturel cycle in nature? A little bit like carbon or azote. In other word does radiation help the environment?
Naturally occurring does not mean it's healthy, required, good, nor helpful.
@blusafe1 I think I see what you mean.
How do the things that are naturally there , even if they seem bad/not practical, interact with nature?
When my teacher talked about lakes and how warm water can over transform the lake into what I can only describe as "ground." I feel amazed and pragmatic about what good or bad? Well... in that case it's bad but, it a byproduct of some industry. 🫤
Nearly all the radioactive material on earth is naturally occurring, and there is always more being made from Cosmic rays hitting earth (ex: radioactive Carbon-14).
The generally “Good radiation” is what powers photosynthesis in plants, is the light we use to see, the warmth we feel from the sun; and safely carries our cellphone’s radio signals so we can communicate.
The generally “Bad Radiation” *above specific levels of exposure* include high-energy Gamma rays, X-rays, Ultraviolet light. And, of course the byproducts of radioactive material decaying over time. ex: Carbon-14 decaying into stable Nitrogen-14 will release a tiny amount of harmful beta particles. Others byproducts include alpha particles and neutrons.
Essentially, all types of radiation can both hurt and help the environment. It all depends on the context.
The controlled amount of neutron interactions used to keep a nuclear power plant running, helps the environment by replacing Climate Change causing Coal power plants. [burning Coal can also release harmful radioactive Iodide, which contaminate both plants and animals]
The controlled release of massive amount of neutrons, *into highly enriched uranium/plutonium/etc…*, is what ultimately drives a nuclear bomb to detonate.
They both use the same basic process, but only nuclear power production helps lower our Greenhouse Gas Emissions and makes using electric vehicles/trains a truly clean decision.
This could’ve been an hour long - slowed down a bit- and explained in a way that didn’t leave me saying, “Huh? What?”

Hilarious.
Fukushima was in 2011 not 2013
