Radioactivity

will be images, combined with genes, tumor markers and patient data.” (Liselotte Hojgaard, MD, professor of medicine and technology at the University of Copenhagen) The science of radioactivity has existed for many decades since it’s discovery. While often perceived as a risky and dangerous practice, artificial radioactivity can not only be used for energy and weaponry, but also to diagnose diseases and cancers, and even heal them. The introduction of nuclear medicine began in the mid 1920’s…

The Manhattan Project was a research and development project undertaking during World War 2 that produced the first nuclear weapons. Some people believe that the dropping of these atomic bombs and the development of the Manhattan project was very necessary and it needed to be done. But on the contrary, some think it was a waste of money, time, and it was not used for the good of the war and it was dropped on thousands of innocent people. The Manhattan Project was a great step in gaining…

themselves. A Fallout shelter is a civil defense measure intended to reduce casualties in a nuclear war. It was designed to allow those inside it to avoid exposure to harmful fallout from a nuclear blast and it’s likely aftermath of radiation until radioactivity has dropped to a safer level. A basic shelter consists of shielding that reduces gamma-ray exposure. Even today many people are building these massive inground bunkers. Japan wasn’t so lucky as to begin preparations for the bombs. The…

The presentation, aptly named Manya after Marie Curie Sklodowska’s childhood nickname, was an impressive story telling of the life up to the beginnings of World War I of the Nobel Prize winning Chemist and Physicist Marie Curie Sklodowska. The presentation itself took place in Boettcher lecture hall 102 but was dressed up nicely to match important periods in the life of Marie Curie. The set consisted of a small table which held several notebooks and correspondence that were of import to Curie,…

Uranium Paetyn Blockhus Why do you think people thought when they first discovered uranium? The warfare has changed when uranium was introduced. The discovery of radioactivity and other things in uranium has been discovered over the years. The size and weight of uranium is one of its many characteristics. The world had changed when they started using and mining uranium. The fun facts of uranium are truly surprising. Uranium is an…

nuclear tests. In 1965 and 1957 there were many cases of radiation caused cancer in the Morman community. There is a local realization that living downwind from test sites causes birth defects, miscarriages, thyroid issues, and leukemia due to radioactivity. Public pressure began to grow to stop nuclear testing when childhood leukemia and other cancers increased and when scientists found radioactive strontium in baby teeth of…

leukaemia. Among pregnant survivors, there were teratogenic effects on foetuses which resulted in birth deformities and stillbirths over the next 9 months. (World Nuclear Association, 2014) Today, the radioactivity in Hiroshima and Nagasaki is so miniscule that it is difficult to distinguish from radioactivity caused by the nuclear fallout after the explosion as opposed to underground atomic-bomb tests that were conducted around the world in past decades, particularly in the 1950s and 1960s.…

field of chemistry and physics at the university. A very important part in Marieś scientific development was when she started looking at the radioactive materials of objects. She said that radioactivity was an atomic property and knew it had to be in some elements. She actually invented the word radioactivity after her studies. She discovered two new elements in search of radioactive objects. These elements were radium and polonium, which was named after Poland. Marie has numerous awards and…

The most devastating environmental event caused by humans was the Chernobyl disaster. Chernobyl is an entire city that had a nuclear accident causing damage to the surrounding area for miles. Chernobyl had many different effects on the environment. The accident was a man made occurrence and could have been prevented. Some of the effects on the environment was reduction of biodiversity, by killing and mutation of plants and animals. These are just some of the reasons that chernobyl is the worst…

radioactive. This radioactivity is also something experienced by the production of electricity by nuclear power. Though little and containable, the waste produced by nuclear reactors needs to be disposed of safely because they can leak radiations and this is done through tedious and expensive methods. Also nuclear radioactivity has a disastrous effect on aquatic life if neglected. “Reports say that radioactive wastes take almost 10,000 years to get back to the original form”(Risks) and…
