At present, there is extreme politics and Energy competition around the world regarding Uranium.
According to the World Nuclear Association, the universe's uranium supernova was formed 6.6 billion years ago. It covers the entire planet and mostly forms 2 to 4 parts per million rocks. According to the USA Department of Energy, natural crystal is the 48th most abundant element found in natural stone and is 40 times more abundant than silver.
Uranium is the key tool in the power struggle on the Earth
Although
radioactivity is involved with uranium, its rate of decay is so low that it is
no longer one of the radioactive elements. Uranium-238 has an incredible
half-life of 4.5 billion years. Uranium-235 has a half-life of only 700 million
years.
Uranium-234 has the shortest half-life of 245,500 years, but it is indirectly affected by the decay of U-238. In comparison, the most radioactive material is polonium. It has a half-life of only 138 days.
Nevertheless, uranium has the potential to explode, thanks to its ability to maintain a nuclear discipline response. U-235 "fissile", meaning its nucleus can be split by thermal neutrons. Here's how neutrons work with the same energy as their surroundings, according to the World Nuclear Association:
The nucleus of a U-235 atom has 143 neutrons. When a free neutron enters a molecule, it splits the nucleus and throws out extra neurons, which can subsequently shake into the nucleus of the U-235 atom to form a self-sustaining cascade of nuclear dissociation. Each of the split events generates heat.
In a nuclear reactor, this heat is used to boil water, create steam that turns turbines into energy, and the reaction is controlled by materials such as cadmium or boron, which can take in extra neutrons to get out of the reaction chain.
To make uranium fission more efficient, nuclear engineers enrich it. Natural uranium is about 0.7 percent U-235, a physeal isotope. The rest is U-238. To increase the U-235 ratio, engineers gasified or used centrifuges to isolate isotopes. According to the World Nuclear Association, the richest uranium for nuclear power plants consists of 3 percent to 5 percent U-235.
At the other end of the scale is depleted uranium, which is used to make tank armor and bullets. What is the key to depleted uranium after enriching uranium in a power plant? According to the U.S. Department of Veterans Affairs, it is about 40 percent less radioactive than natural uranium. This depleted uranium is only dangerous when inhaled or ingested during shooting or exploding.
Uranium is sometimes used for stained glass, which glows greenish-yellow under black light - but not because of radioactivity (the glass is only the smallest bit radioactive). According to the collector's weekly, the reflection makes the glass uranyl compound attractive because of the UV light, as it blocks the photons as it settles backwards.
According to the World Nuclear Association, uranium is mined in 20 countries, more than half of which come from Canada, Kazakhstan, Australia, Niger, Russia and Namibia. For the most part, the general public can safely ignore the amount that has been injected, unless they are grown on hazardous waste sites, mines, or crop contaminated land or mixed with contaminated water.
