Improving the health care system can play a crucial role in the delivery of safe, cost effective patient care. Many governing bodies mandate quality improvement in healthcare. Quality improvement initiatives are a result of systems failure. A thorough investigation into the failure can reveal where and how the system can make improvements. Collection of data is essential for evaluation of quality improvement measures. This document will examine a quality improvement issue with…

One of the main experiments Rutherford is known for is his Gold foil experiment. He devised a way to prove that radioactivity in particles exists in at least two forms. In the experiment tiny alpha particles were shot at a sheet of foil coated in ZnS which resulted in a small percentage went through the sheet and the rest were blocked/deflected. The percentage of particles that were able to go through the foil are now named 'Alpha Particles' and the ones that were blocked are called 'Beta…

antidepressants and antipsychotics is not recommended and should be discontinued 48hrs before any procedure and for at least 24hrs post-procedure. If the patient is under any of these medications during a procedure to diagnose thyroid disease and iodine isotopes are being administered the iodine-binding capacity of thyroid tissue may be reduced for up to 2 weeks after contrast medium administration. Routes of administration for the drug omnipaque may vary depending on what exam is going to be…

In forensics, there is a lot of chemistry involved. The various processes that a forensic procedure requires includes basic skills and knowledge from chemistry. Since chemistry and forensics are so closely related, many of the same concepts are used in each field. That is why it is important to go into more detail to see what type of chemistry has to deal with this. It is very rare that there is a forensics specialist investigating a crime scene without there being any type of chemistry…

In the last 60 years, Uranium mining has become the basis of one of the worlds most popular sources of energy. While Uranium is almost always used for nuclear energy, it is also used in medical isotopes. To obtain Uranium for nuclear power, it is generally mined in large open pit and underground mines. Like most other mines, mining Uranium destroys the ecosystem and landscape, produces lots of noise pollution, demolishes habitats and are very dangerous. More specifically, Uranium mines have an…

Have you ever wanted to buy an element from the periodic table? Well you found the right place. I sell Sulfur for a living may not be the right or cool thing to sell but I sell it. You can use my wonderful Sulfur to make cleaners and to make car batteries. This element is the easiest to find on the periodic table all you have to do is look for the letter (S). Let’s learn about the discovery of this wonderful object. This wonderful Sulfur was discovered around 1777. The special person that…

Nuclear fuels derived from plutonium-239 and uranium-235 contains numerous carcinogenic radionuclide isotopes. Some of these isotopes include iodine-131, strontium-90, and caesium-137 (Imura, 19). Furthermore, it also comprises of some transuranic elements and other isotopes from plutonium. Some of these long-lived radioactive materials have a profound effect on humans and the environment if left unprotected. They are supposed to be stored…

The search for a form of power that is almost completely renewable and its energy output far exceeds the energy required to start and maintain the reaction has been a focus for many years. Energies that are present today that involve burning things to produce electricity, such as coal, produce tons of pollution at a worldwide level. One of the newest energy sources being researched is a nuclear fusion reactor. This type of power generation has the ability to satisfy this search for a sustainable…

Selenium: The Essential Element Introduction Over the years, selenium is known to be the essential element in all forms of life. Selenium is a metalloid belonging to the block p, group 16, period 4. It is a gray metallic rare element widely distributed within Earth’s crust which has an atomic number of 34 and a symbol “Se”. Selenium was discovered in 1817 by Jöns Jacob Berzelius and Johan Gottlieb Gahn after analysing an impurity contaminating the sulphuric acid being produced by a factory…

Tungsten is very abundant most tungsten production come from China which it is then put on the tips of mining drills. In Encyclopedia Britannica in Britannica School, tungsten has five stable isotopes, tungsten-180, tungsten-182, tungsten-183, tungsten-184, and tungsten-186. There is no radioactive isotope in tungsten that decays into anything. It belongs to group VI-B on the periodic table. In Facts on File in Science Online, pure tungsten is used in light bulbs and x-rays, while others…
