Radionuclide

used as tracers or therapeutic agents in medicine; these are 123-I, 124-I, 125-I, and 131-I, with the latter being the most common in clinical practice. Essentially all industrial production of radioiodine isotopes involves four aforementioned radionuclides. History of radioiodine production and usage The first radioiodine was produced by Enrico Fermi in 1934. It was Iodine-128, which prompted additional experiments in France and the United States. Karl Compton and the thyroid group from the…

roughly two times larger than what the plant was designed to handle. The crippled reactors melted, resulting in the largest nuclear accident since Chernobyl. Land within 20 kilometers of Daiichi is now uninhabitable, and water contaminated with radionuclides has been leaking into the Pacific Ocean since March 2011. If the Japanese public decides nuclear technology is not to be trusted, they may abandon nuclear energy as a source of electricity altogether. The disaster at Fukushima…

Even though utilizing nuclear fission as a power source does have its respectable pros, the cons seem to overwhelm the pros. Setting up nuclear power plants is very expensive and the majority of nuclear power plants’ fuel relies on a very meager source. The other cons include and are not limited to: mining for the meager source poses a health risk to the people mining and not mining and if not dealt with properly, the radioactive materials used in a nuclear power plant can severely harm the…

your body and your needs. A lot of hospitals and dentist offices use radiation in a wide range of ways like in x-rays, and doctors use it in these, PET machines, dialysis, radionuclides and a lot of other important things. PET machines are used to produce detailed images of the human body and help find diagnostic. Radionuclides are made to treat illnesses such as cancer or hyperthyroidism. So without theses machines that require radiation we wouldn’t be able to find out diagnostics or illness.…

Abandoned and active radioactive mining and storage facilities in proximity to Western Native American Lands pose environmental and extreme health risks to Native Americans. In the past governmental agencies have failed to educate Native American people of the dangers of radioactive waste, and have been neglectant in the clean up of many sites. In certain communities such as, Paguate and the Navajo Nation, there is a high prevalence of cancer and various respiratory diseases in residents living…

Introduction Nuclear disasters can be held responsible for leaving the greatest and longest lasting impacts on an environment. One of the most infamous nuclear disasters in the world’s history would be the Chernobyl Nuclear Explosion. On April 26th, 1986, the 4th reactor of the V.I. Lenin Nuclear Power Plant in Chernobyl, Ukraine exploded, allowing for innumerable amounts of toxic radiation to be spewed into the air. Radioactive contamination was spread over 100,000 square kilometers of land…

The term “nuclear engineering” often denotes connotation of war derived from the use of atomic bombs at the end of World War Two. Wartime often heavily influences the intention of research and World War Two was no different. Although, outside of war, nuclear engineering’s emphasis is as a source of power. With the turn of the 21st century, realization of increasing energy demands, awareness of the importance of energy security, and concerns about global warming have surfaced. With such…

INTRODUCTION In the world 17% of the total electrical energy is generated by nuclear energy, but with the creation of nuclear energy produced many concerns for the surrounding environment. Nuclear waste is produced in different forms with different chemical and physical properties. This waste may be: • In the form of gas emitted from radioactive materials • In the form of liquid excreted from many research fields • In the form of solid ranging from glassware of hospitals and contaminated trash…

could help human and make life better, and with more advanced technology. These technologies are for example, cardiac catheterization and radionuclide imaging (Tanser, 2006). These devices are used to treat and prevent serious illnesses. Cardiac catheterizations prevent human body from heart attack and treat any problems with artery and vein pulmonary. Radionuclide imaging is a sending of a substance to the vein by injection and these substances emit gamma rays. The gamma rays could be detected…

What is the most important element of an engineer’s job? Speed or safety? There is no doubt that most engineers choose the public’s safety as their first priority instead of speed, for even a small difference between draft and reality can lead to engineering disaster. For some engineers who hold the speed as the highest goal, they had left several sever disasters caused by flaws in their engineering design; from their unforgettable experience, engineers put more thought in to the design before…
