    Uranium
In summary, Americium is significantly more expensive than Uranium due to its rarity and the difficulty in extracting it from spent nuclear fuel. While Uranium can be mined from the ground, Americium must be extracted from spent fuel, with a yield of only 0.01%. Additionally, the handling of spent fuel is more complex and costly due to its higher radioactivity.

The cost of Americum:

Cost, pure: $1500 per g (1,5 million USD per Kg)
Cost, bulk: per 100g

The cost of Uranium:

US $ 51,5/lb (at 25.07.2011) or 11,3 cents per gram (natural uranium in the form of the unrefined oxide U3O8).

Why is Uranium so much cheaper?

If you look for Americium (and not Americum) you may find some information in wikipedia.
In contrast to uranium, Americium does not occur in nature which explains it's high price.

You can dig uranium ore out of the ground. You have to extract americium from spent fuel for nuclear reactors. According to the Wikipedia article, one ton of spent fuel yields about 100g of americium. That's a ratio of about 0.0001 or 0.01%. And spent reactor fuel is a lot more radioactive than uranium ore, hence requires more care (and cost!) in handling.

FAQ: Why is Americum more expensive than Uranium?

1. Why is Americium more expensive than Uranium?

Americium is more expensive than Uranium because it is a man-made element that requires a complex and expensive process to produce. It is not naturally occurring in significant amounts, unlike Uranium which can be found in nature.

2. What is the main use of Americium that contributes to its higher cost?

The main use of Americium is in smoke detectors, where it is used as a source of ionizing radiation. This requires highly purified and controlled amounts of the element, making it more expensive to produce.

3. Is Americium more rare than Uranium?

No, Uranium is actually considered to be a rare element. However, Americium is even rarer as it is only produced in small quantities through the decay of other elements, making it more difficult and costly to obtain.

4. Can Americium be used as a fuel for nuclear reactors?

No, Americium cannot be used as a fuel for nuclear reactors. It is not a fissile material, meaning it cannot sustain a nuclear chain reaction. It can, however, be used in small amounts to enhance the performance of some types of nuclear reactors.

5. Are there any other factors besides production costs that contribute to the higher price of Americium?

Yes, there are other factors that contribute to the higher price of Americium. These include its limited availability, strict regulations on its handling and use due to its radioactive properties, and the specialized equipment and facilities required for its production and storage.
