Irradiated Thorium is more dangerously radioactive in the short term. The Th-U cycle invariably produces some U-232, which decays to Tl-208, which has a 2.6 MeV gamma ray decay mode. Bi-212 also causes problems. These gamma rays are very hard to shield, requiring more expensive spent fuel handling and/or reprocessing.
for instance, Is thorium a rare earth metal?
Rare earth elements, known as lanthanides and actinides on the periodic table, include 15 chemical elements with atomic numbers 57 through 71. … Rare earth minerals are processed primarily from ores and minerals that naturally contain uranium and thorium.
significantly, Which country has most thorium?
Australia has the highest thorium resources with 489,000 tons followed by the US with 400,000 tons, Turkey with 344,000 tons and India with 319,000 tons. The remaining resources are found in countries like Venezuela, Brazil, Norway, Egypt, Russia, among others.
also Does thorium produce waste?
Thorium is three times more abundant in nature than uranium. … Compared to uranium reactors, thorium reactors produce far less waste and the waste that is generated is much less radioactive and much shorter-lived.
How much thorium do we have left? The report raises the question how much thorium is recoverable at a price of 500$/kg in 1969 dollars, perhaps 3000$/kg today. The answer is 3 billion short tonnes or 2.700. 000.000 metric tonnes, enough to last us 40.000 years in our extreme scenario.

Is Lithium a rare earth metal?
A lot of these warnings have been incorrectly categorized under “EVs and rare earth metals.” Though neither lithium nor cobalt are rare earth metals, and rare earth metals aren’t nearly as rare as precious metals like gold, platinum, and palladium, there are important issues surrounding the production of lithium-ion …
Is scandium a rare earth?
Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. While named rare earths, they are in fact not that rare and are relatively abundant in the Earth’s crust.
Can you invest in thorium?

Can a thorium reactor meltdown?
Most importantly, meltdowns aren’t possible with thorium reactors because the reaction is not self-sustaining. That last safety advantage is also the main drawback of thorium. You need a little uranium and a neutron source to get the reaction kickstarted.
Why is thorium not used for energy?
Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – ‘so these are really U-233 reactors,’ says Karamoskos.
What is the rarest birthstone?

What’s more precious than a diamond?
Emeralds are rarer and often more expensive than diamonds
When it comes to rare and expensive gemstones, most of us immediately think of diamonds, but, in fact, emeralds are more than 20 times rarer than diamonds and, therefore, often command a higher price.
Is lithium a rare earth element?
Lithium constitutes about 0.002 percent of Earth’s crust. … According to the Handbook of Lithium and Natural Calcium, “Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations.
Does Tesla use rare earth metals?

Do lithium batteries use rare earth?
Explanation: Many EV critics will portray the electric battery as toxic and dependent on a number of rare earth metals mined from conflict regions. It is true that cobalt and lithium are widely used in many EV batteries; however, neither are rare earth metals.
