The zirconite is one of mineral resources associated with radioactivity.The exploitation and uses of zirconite would lead to pollution to the environment.
After the magnitude of the disaster became clear, so called liquidators were sent in trying to contain the radioactivity and seal the destroyed facility.
This second explosion would have been accompanied by a terrible shock wave and a massive rise in radioactivity that would have claimed thousands of lives in a matter of hours.
All of the water is sent through a powerful filtration system to remove much of the radioactivity and is stored on-site in more than 1,000 giant steel tanks.
Only the 1986 accident at Chernobyl, in Ukraine, has caused mass fatalities from radioactivity, and the plant there was subpar and mismanaged, by Western standards.
But heat from radioactive decay moves so slowly through solid rock that taking radioactivity into account only improves Kelvin's estimate by...pretty much nothing.
Kelvin's error is usually attributed to the fact that he didn't know about radioactivity, which creates a ton of heat in Earth's core and helps keep the planet warm.
