Uranium

How threatening it might sound, nuclear medicine is a very common type of treatment, as “On average, one in every two Australians can expect at some stage of his or her life to undergo a nuclear medicine procedure,” (Australian Nuclear Science and Technology Organization). It may come as a surprise, but these include Nuclear Imaging such as MRI (Magnetic Resonance Imaging), Pet scans, CT (Computerized Tomography) CAT (Computerized Axial Tomography). And no it is not A green liquid in a capsule…

In 1939, a scientist wrote a letter to the President of the United States, Franklin Roosevelt, which would alter the course of history. This scientist was Albert Einstein – after fleeing from Germany, he was concerned with the possibility of the Nazis succeeded in building a weapon never seen before: an atomic bomb. Einstein encouraged a program to research the prospect of nuclear weapons – the Axis powers gaining access to an atomic bomb would present a catastrophic situation to the Allied…

Humanity is in a race against time as the threat of global warming looms on the horizon. To prevent catastrophe, the nations of the world must focus on decreasing their carbon dioxide output by as much as possible. While agriculture and industrial processes have a high carbon footprint, fossil fuels are by far the biggest contributor to anthropogenic global warming. Therefore, the best way to mitigate the problem is to replace coal and oil with cleaner sources of energy. Solar and wind power are…

the amount of nuclear weapons in the world would have no effect on these people’s desire to build weapons of their own. Additionally, So long as people are aware of the power held within enriched uranium, there will be a black market. Even if worldwide regulations made it more difficult to harvest uranium, people would still seek it out and be willing to pay massive amounts of money for the power it would bring…

If tayo never cared for the cattle he would have never gone onto the white man’s property and would never see the destruction first hand. He also would have never been chased by the police as well never even step foot into the uranium mine. It was essential to chase after that cattle as it led him towards finishing his journey and completing the ceremony. Tayo’s friends were also essential in his path towards healing. Without them he would never realise that their habits are not…

impact on our atmospheres as it does not release any hazardous gases like carbon dioxide, methane etc. which has resulted in the depletion of ozone layer in the atmosphere.But the fight here we have is to produce nuclear energy we have to extract uranium which has been the clean process since ages. Besides, each day technology is seeing improvements to increase efficiency and prevent pollution.In practice, the spent fuel is not anytime unshielded. It is always kept underwater as water is an…

Well, President Roosevelt put together a team of scientist led by Robert Oppenheimer to build this Weapon of Mass Destruction. The bomb was made out of a Radioactive isotope of Uranium, Uranium 235. This Bomb was 2 billion dollars’ worth of research. The Bomb was ten feet in length. On August 6,1945 a B-29 plane named the Enola Gay set out for Hiroshima . Strapped to the bottom was the “Little Boy”, or the Atomic Bomb which was ten…

“targeted” not Tokyo, or How many U.S. Americans died in the atom bomb explosion? These questions will be answered and some other questions that where not mentioned. There are many materials needed to make an atom bomb. First, thing you need would be uranium or plutonium. The two item’s that can be used…

Radio isotopes are atoms that contain an unstable mixture of protons and neutrons. This means that they give off radiation. Some elements like uranium give off radiation naturally but other sorts are made in a lab for specific purposes like radiotherapy for the treatment of some sorts of cancer. Radiation as a medical treatment has been around for a long time. X-Rays as such were discovered in 1896 by Wilhelm Roentgen and as early as 1901 low dose X-Rays were being used to treat cancer. It…

The bombing of Hiroshima and Nagasaki are among the most horrific and devestating works of mankind. Millions of Japanese civilians were killed, their bodies either evaporating from the strength of the atomic bomb or crushed under fallen buildings. Years later, the effects of the bombings could still be observed with people dying from cancer and infants born with birth defects - all as a result of radiation. However, the bombs were used for specific purposes and answered the questions that…
