After 24,10(3) days (the half-time of this isotope) the mass is 50 %.
India has 25 % thorium of the world.
Half the original amount.
You cannot compare ounces (mass or weight) with gallons (volume).
25 gExplanation:Think about what a nuclear half-liferepresents, i.e. the time needed for an initial sample of a radioactive substance to be halved.
Yes, we can get more electricity from thorium, if you are asking about the supply. When 232Th is used in a nuclear reactor, it is bred to become 233U. This isotope of uranium has about as much energy available as 235U, so the amount of energy per fission event is about the same for thorium as it is for uranium. Aside from that, however, there are important differences. Thorium does not need to be enriched, so all of it can be used. The amount of thorium we have is a multiple of the amount of uranium. The combination means that, where we only have a few decades supply of uranium, we have enough thorium to last thousands of years.
The half life of thorium-232 is 1,405(6).10e10 years.
Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
Bitumen has not thorium.
India has 25 % thorium of the world.
Thorium is not expensive; for thorium dioxide (99,99 %) the price is cca. 0,1 USD/g.
Ceramic bowls for kitchen, with thorium, doesn't exist.
Half the original amount.
Approx. 50 USD/pound for thorium dioxide (99,99 %).
One-half of the original amount. That's precisely the definition of "half-life".
United States has thorium reserves of approx. 160 000 t.
One quarter.
When not mixed with clay, about 0.02% (depending on the type of thorium compound)of ingested Thorium is absorbed into the body but since Thorium is strongly adsorbed by clay, the absorption of ingested Thorium mixed with clay soil is negligible, much less than 0.02%.
