Tp Lung: How Uranium Enters Our Body

Urainum-238 has a half-life of around 4.5 billion years, meaning that half the atoms in any sample will decay in that amount of time (4.5 billion years). Uranium-238 emits alpha particles which are less powerful than other forms of radiation, and weak gamma rays. As long as it remains outside the body, uranium poses little health

Issue: In medicine, radioisotopes are bonded with chemical compounds to form radioactive tracers, which are then injected into the patient’s bloodstream. The radiation emitted by the tracers allows doctors to obtain images of organ systems, facilitating the early and accurate diagnosis of disease. However, to avoid radio- active contamination, care must be taken in the storage, use, and disposal of this material.

The United States tested nuclear bombs, “215 A- and H-bombs” (www.nukewatch.com) above ground between 1951 and 1963 in the Nevada Test Site. Fifty years later, the U.S government studies stated that over 80,000 people who lived or were born in the U.S suffered from cancer caused by radioactive fall-out from nuclear testing. Over 15,000 of them died. Many of whom were from the states close to the testing sites, called the “downwinders,” Utah, Idaho and other states. From the Nevada Test Site the winds carried nuclear radiation fallout, filled with “iodine-131” which caused “75,000 thyroid cancers, ten percent of which are estimated to have been fatal, and strontium-90 and cesium-137, which are dangerous for between 280 and 300 years,” (nukewatch) likely causes of bone and skin cancer and leukemia. Therefore, there is some strong evidence that nuclear fall-out in the 1950s did cause cancer.

Characters bring a variety of purpose and perspectives to a story. Some characters stand out more than others; some have more depth, while in contrast some have less. In most cases, we become primarily familiar with the main characters in a narrative. Dominican-American writer, Junot Daz, employs a main character who brings a youthful perspective in his short story The Money. This narrative entails a twelve-year-old boy, Yunoir, and his experience of his impecunious immigrant family’s apartment in New Jersey being robbed while on vacation.

Boxer and Napoleon are two very different characters; they are not similar in any way. Boxer cares about the animals and would do anything for them and Napoleon only seems to care about himself and thinks of the animals as slaves. The animals on the farm seem to respect Boxer very highly but they are terrified of Napoleon and his bodyguards. The animals, because of their respect for Boxer, would do anything for him out of their own good will, but the only reason that they might do anything for Napoleon is because they know if they don't, Napoleon will do something to them, or maybe not give them any food. Although for Boxer this is not true because he is a gullible character and trusts Napoleon with his life and would do anything for him.

In today’s society Dieting and Exercise are very important in obtaining good health. Regular exercise has been long associated with fewer visits to the doctor, hospitalization and medication. Stomach cells regulate several functions such as sensation, motility, secretion, absorption, local immune defense and also your food intake. Many physicians today use dieting as an intervention to overcome health disorders and diseases such as crohns disease. Crohns disease is a chronic disorder that is associated with inflammation of the digestive tract. Over half a million Americans men and women have been diagnosed with crohns disease. Crohns disease is the most frequent functional gastrointestinal disorder, with a prevalence of 5% to 11%, and is associated with high cost of health care and reduced quality of life (Ligaarden & Farup 2011). Some environmental factors such as dietary factors and psychological stress can play a huge role on the clinical course of crohns Disease. More than two thirds of subjects with CD relate their symptoms to the intake of food, leading most patients to modify their diets ( Ligaarden & Farup 2011). Psychological stress has played a role in causing

The Navy’s testing included napalm, a mixture of a gelling agent and petroleum or a similar fuel for use as an incendiary device; and depleted uranium, a radioactive strain of uranium with a lower content of a fissile isotope U-235, substances which the Navy originally denied using. In 1999, the Navy admitted that it tested 14 napalm bombs on Vieques in 1993 and that depleted uranium (DU) tipped ammunition was first testing in Vieques 1980. Between 300 and 800 DU weapons were tested during the Gulf War. Because of high temperatures, uranium is released in a radioactive cloud. A single particle of DU can be lodged in the human lung, where it will give off eight hundred times the radiation considered safe by US regulations. 3 DU exposure includes: reactive airway disease, neurological abnormalities, kidney stones, chronic kidney pain, rashes, vision degeneration, leukemia, lymphoma, birth defects, and gastrointestinal

It is now known that radium, shown in figure 4, is a potent carcinogen (a substance the cause’s cancer (Wilbraham, Staley, Marta, & Waterman, 2005)). It emits a form of ionizing radiation which “includes electromagnetic radiation (e.g., gamma rays and X-rays) as well as particles (e.g., alpha particles, beta particles, high-speed neutrons, high-speed electrons, high-speed protons, etc.)” (National Library of Medicine, n.d.). Acute studies have been done on the effects of radium exposure on the human body by organizations like the Geneva World Health Organization, the International Agency for Research on Cancer, and Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Man. As a result of their findings, The National Library of Medicine states that sufficient evidence has been provided showing that prolonged exposure to Raduim-224, Radium-226,

Pentetic acid (diethylenetriaminepentaacetatic acid, DTPA) is an effective decorporation agent to remove actinide. DTPA has been proven high decorporation efficiency of plutonium in humans[3,6,7].In comparison to DTPA chelates formed with essential metals, the actinide DTPA chelates are much more stable and easier to be excreted in urine.

Cancer is a genetic, heritable disease in which abnormal cells divide rapidly destroying normal body cells, often being fatal. Cancer can occur in any body tissue; skin, organs, and parts of the reproductive system (Duda). There are various activities linked to different types of cancer, such as smoking, too much sun exposure, gene mutations, carcinogens, and viruses. A major cause of cancer, dating all the way back to the 1950’s, is radiation. Atomic testing ordered by the U.S. Government has been suspected to be the cause of many deaths linked to radiation-related diseases (Williams 149).

It is not until recently that people have become dependent on this element, and not necessarily for the good of it, and the world. There is an obsession with uranium because of its unique properties. Uranium is extremely powerful because of its radioactive properties and unstable nuclei, especially that of Uranium-235. It is able to break down and release high frequency radiation through alpha and beta decay. It is because of these characteristics that Uranium has such a craze on the population of the world (Cox, 1995; Scerri, 2007). The properties of uranium allow people to create powerful plants to produce electricity, and weapons strong enough to destroy the world.

There are many advantages and disadvantages to the use of radioactive elements in medicines. Some advantages include the fact that

Depleted Uranium is a significant problem that is harming innocent people. People who are living in heavily militarized areas are getting the worst of it. The people living in the city of Fallujah are trying simply wanting to live and the use of DU as a conventional war weapon is destructive by killing people, or compromising their health. It makes it difficult to go to work when a person develops cancer and is too tired and sick to get out of bed. For a women to be pregnant and after giving birth realizes her baby has serious deformities is heartbreaking. Fallujah is one example of a population severely affected by the use of depleted uranium. Furthermore, the lack of information and unwillingness by the United States government to recognize

It was brought over from the United Kingdom and evolved into many different forms. Has been credited with killing one thousand four hundred sixty three people since 1976. No, I’m not talking about a disease such as the bubonic plague, measles, and tuberculosis but about the death penalty. Since the reinstatement of the death penalty in 1975 a debate has begun on whether we should or shouldn’t support the death penalty. (Sentence on why people support it or not)
