Isotope

The other material that is available to use is Plutonium-239. The Nagasaki bomb used this type of material which generated a destructive energy equivalent to 21,000 tons of TNT. Those two materials was selected because both of them have an unstable isotope which make them have a high radioactivity level.…

Scientists use radiation in more forms than the average person realizes. With new technology these developments form new ways of living. Agriculture is not recognized as a big part in nuclear science. George de Hevesy was the first to practically use an isotope in 1911. We can thank him for the new advancements in fields of nuclear technology. The food you eat probably was altered using a form of neutron or gamma irradiation. Radioisotopes have changed the way we live, through all fertilizers,…

Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident on March 11th 2011 that would reintroduce to the world the question of “Should the use of nuclear energy continue?” Fukushima and many other critical junctures since the start of the first nuclear reactor in Idaho, in December 1951, have influenced changing attitudes towards nuclear energy throughout time. Nuclear power is one of the primary…

was based on the stable isotope labeling by amino acids in cell culture (SILAC) experiment whereby the Iscove’s modified minimal medium (IMEM) was custom prepared based on the ATCC formula without L-lysine or L-arginine. However, the complete light and heavy IMEM media was prepared in the addition of light and heavy lysine and arginine along in dialyzed FBS. The collected HL-60 cells were cultured in heavy IMEM medium for five cell doublings to achieve a complete isotope incorporation. The…

likely be classified in grade 4 for severity meaning that she is very severe o Grade 4 : >50% retention after 4 hours • Other diagnostic tests for gastroparesis include: Radiopaque markers, Ultrasonography, MRI, single photon emission CT, stable isotope breath tests, swallowed capsule telemetry, antroduodenal manometry, and EGG 4. What are the common signs and symptoms of gastroparesis? Explain how they may lead to nutritional deficits. • Common signs and symptoms include: Nausea,…

Invisible Yet Deadly In 1938 German Otto Hahn and his assistant Fritz Strassmann discovered that when uranium is bombarded with neutrons, through the process known as fission, there are two lighter elements, neutrons, and a large amount of radiation produced. It was clear that these neutrons could in turn also cause fission, producing more neutrons and developing a chain reaction which might spread throughout all the uranium present (Rinkesh). This fission reaction showed a lot of potential,…

and the contrasts amongst Betadine and Iodine in detail. What is Iodine? Iodine is a synthetic component (I-53) and it is a somewhat blue dark hued strong under standard conditions. It exists as a diatomic atom (I2) having just a single stable isotope. The word Iodine is a Greek word, which means purple or violet. Iodine has been being used for over 170 years as a very powerful antimicrobial operator in clinical medications.…

After receiving his Ph. D., Dr. Seaborg spent time as a personal laboratory assistant to G. N. Lewis, from 1937 to 1939, where they published some scientific papers together. During this time, Seaborg collaborated with John Livingood to create an isotope of iodine, iodine-131, which is used to treat thyroid disease.…

How Uranium affects TP53 Do we know how Uranium affects TP53 to affect our bodies? Uranium is a dense radioactive metal, that is used as fuel in nuclear reactors. Uranium has several isotopes, and the most important of these, are radioactive and presented in nature. This radioactive substance affects our bodies in many contrasting ways. Examples are, our organs, DNA, our tissue, bones, and TP53 gene. In this paper, we will focus most on how Uranium affects TP53 to affect our body. The official…
