Approximately 85 percent of diagnostic imaging procedures in nuclear medicine use this isotope. Technetium-99m is made from the synthetic substance Molybdenum-99 which is a by-product of nuclear fission. It is because of its parent nuclide, that Technetium-99m is so suitable to modern medicine. Molybdenum-99 has a half-life of approximately 66 hours, and decays to Tc-99m, a negative beta, and an antineutrino. This is a useful life since, once this product (molybdenum-99) is created, it can be transported to any hospital in the world and would still be producing technetium-99m for the next week. The betas produced are easily absorbed, and Mo-99 generators are only minor radiation hazards, mostly due to secondary X-rays produced by the…

Back then, the Ancient Greeks and Romans used alum as an astringent, for medicinal purposes, and as a mordant in dyeing (N/A, 2012). Today, it is used in kitchen utensils, exterior decorations, and thousands of industrial applications. The uses of the element can vary from being kitchen foil, to being used to create planes and trains. Aluminum is also used in electrical transmission lines because of its light weight, and its alloys are used in the construction of aircraft and rockets (Helmenstine,…

In 1809, J. Maggiolo inserted a gold implant tube into a fresh extraction socket which was allowed to heal and later a crown was added. But unfortunately, there was extensive inflammation of the gingiva which followed the procedure. Innumerable substances during this time period were used as implants; these included silver capsules, corrugated porcelain, and iridium tubes.13,14 Dr. EJ Greenfield15, in 1913, placed a “24-gauge hollow latticed cylinder of iridio-platinum soldered with 24-karat gold” as an artificial root to “fit exactly the circular incision made for it in the jaw-bone of the patient”. In the 1930’s, two brothers, Dr. Alvin and Dr. Moses Strock, experimented with orthopedic screw fixtures made of Vitallium (chromium-cobalt alloy). They carefully observed how physicians successfully placed implants in the hip bone, so they implanted them in both humans and dogs to restore…
One argument for continuing research is that it helps diagnosis injuries and prevent further damaging if diagnosis are early. Not only is this benefit for the patient but it may save the health care system more money as the patient would not need to go for more costly medical treatment if diagnosis are caught early. On the other hand, an argument agasint continuing research is that the cost are increasing at an alarming rate (such as the Large Hadron Collider (LHC), the average person may not see a used for further research in the atomic structure that would affect them directly. Furthermore, the issue shouldn't be about the high cost of research but the accessibility of imaging technology. In a report where they found that well-off Ontarians were 38% more likely to have MRIs done than their poorer counterparts should be examined and should be the issue.…
During the first and second world wars while men were leaving their homes to fight in foreign places, women recognized their additional responsibility to fill the empty spaces in the workforce. In the midst of the Depression, more women were also motivated to go find jobs and assist in supporting their families financially. But what kind of work did these women do? As employers began to recognize these factors, more jobs in which women were able to excel were created, one of which was dial painting. This involved painting watch dials with a newly created paint containing radium, work that required the small, precise hands and keen eyes of girls in their late teens and early twenties (Graebner, 1998). These jobs were made not only to cater to…
September 6, 2000, I was born into this world the 2nd child of Maria and Percy Vela on one typical day there baby boy just like any other newborn, healthy weight and size, but unexpectedly the baby became unordinary. This family went from having a healthy beautiful baby boy to a sick infant who wouldn’t digest anything he was fed and vomited frequently, and it was a nightmare for my parents as they brought me to the hospital in Stamford Connecticut the doctors gave my parents only one option, surgery. This surgery saved my life which laid the groundwork for the person I am today, my view on society, knowledge, work, love, and happiness, the things that have taught me about life.…
Antimony has many universal applications that are meant to be beneficial to people. One of its usages is in its form of antimony trioxide, is made into a flame retardant frequently used in toys and seat covers. Of its many functions, antimony is commonly used as an alloy to make other metals stronger. It is primarily alloyed with lead to make it harder. Its alloys are frequently used in batteries and cables. It is also used in some food packaging, usually used as a catalyst in manufacturing polyethylen terephthalate.…
The first prototype is made of aluminum alloy. Although titanium is the ideal material for any space project, but the cost is much higher than aluminum. Also aluminum is much lighter than titanium, however it has less strength. Its main advantage is the ability to handle extreme low temperature, which is the…
Barium is a soft, heavy, silver-colored metal element. This element does not have very many uses outside of the laboratory, but it combines easily with other chemicals to form compounds used for important industrial uses. For example, Barium carbonate is used in the manufacture of ceramics and special glass, and also to purify certain chemical solutions. It is also an ingredient in clay slurries, also known as water muds, used in drilling oil wells. Barium titanate is used in sonar detectors and other electrical equipment. At low doses, barium acts as a muscle stimulant and at higher doses affects the nervous system eventually leading to paralysis. Acute and subchronic oral doses of barium cause vomiting and diarrhea, followed by decreased heart rate and elevated blood pressure. Higher doses result in cardiac irregularities, weakness, tremors, anxiety, and dyspnea. A drop in serum potassium may account for some of the symptoms. Death can occur from cardiac and respiratory failure. Acute doses around 0.8 grams can be fatal to humans. Barium nitrate makes signal flares burn with a green flame. Barium ferrite is used to make magnets. Barium sulfate is an extremely insoluble barium compound that is not poisonous. Doctors use it in X-ray examinations of a patient's digestive system. The barium sulfate absorbs X rays to show an outline of the intestines on the developed film. A barium enema is performed to examine the walls of the colon. During the procedure, a well lubricated enema tube is inserted gently into the rectum. The barium is then allowed to flow into the colon. The flow of the barium is monitored by the health care provider on an X-ray fluoroscope screen. The test is used to detect colon cancer. The barium enema may also be used to diagnose and evaluate the extent of inflammatory bowel diseases. Barium sulfate and zinc sulfide form lithopone, a white coloring matter for paint. Barium is never found in a pure state because it combines so easily with other…
My element is Thorium (Th). The atomic mass number is 232.038.06 and the atomic number is 90. The melting point is 202./8 K. Thorium belongs to a group called Actinide series.Thorium is a solid at room temperature. Thorium melting point is 2028K, boiling point 5061K, and there is no freezing point. Thorium was found in 1815 by a guy named Jons Jakob Berzelius. It is used alloying agent to improve Magnesium's strength at high temperature. Thorium is also used to coat Tungsten filaments used in electronic devices, such as television. It is used to make glass with a high index of refraction that is used to make in high quality camera lenses. Thorium oxide is used as an industrial catalyst. It is also used for a source of nuclear power. It can…
