Radioactive contamination

Electromagnetic waves are a type of radiation that is produced from electrons (negatively charged particles) and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission.…

chemical and radioactive waste. In which they believe it would be “preserved for eternity” by the snow and ice. However, due to the rise of earth’s temperature the ice has been melting twice as fast. According to Colgan, Greenland ice glaciers have begun melting a month earlier this year. Furthermore, researchers have been studying the US army documents and drawing and have found that the camp has about 200,000 litres of diesel fuel as well as waste water and unknown amounts of radioactive…

Introduction Radiation protection policy is distributed among several governmental Agencies in the United States. Each agency is tasked with controlling exposure to radiation and the safe use of radioactive materials and radiation generating devices. These agencies inform their policy with reports and recommendations from a number of organizations, including the National Council on Radiation Protection and Measurements (NCRP). The NCRP is a longstanding organization that strives to provide…

of the crossbreeding of two hybrid primrose species, Primula verticillata and Primula floribunda. Sedimentary rocks We do not know the actual, or absolute, age of the fossil. We can only infer. Radiometric dating is a process in which a radioactive “parent” isotope decays into a “daughter” isotope. This decay is expressed by the half-life, which is the time that is required for 50% of the parent…

discovered that only certain chemical elements gave off these rays of energy and named this radioactivity. Although Becquerel called this radioactivity, Curie later coined the term “radiation”. She’d be the first to work with radioactive materials and also later discover other radioactive elements such as thorium, polonium, and radium. In 1901 within months of studying and experimenting, systems were being made to use x-rays for diagnosis, and within 3 years radiation was used in to treat…

physicians using radioactive chemicals that examines how fast the food leaves the stomach and goes to the small intestine. Gastric emptying studies are used for checking patients who are experiencing signs of slow and, less commonly, rapid emptying of the stomach. Some signs to watch for are low energy levels, nausea, and heartburn. During a gastric emptying study, the patient eats a meal where the food in the meal and the drink in the meal are combined with a little radioactive material. Then a…

Radiation Burns A burn is an injury caused by an excessive amount of heat. It damages the skin, causing tissue destruction. There are four types of burns; thermal, chemical, electrical, and radiation burns. Someone might get a radiation burn if they are overexposed to industrial ionizing radiation or after doing a radiotherapy treatment. Burns Radiation burns will most likely happen to cancer patients during their radiation treatment or radiotherapy. A response can…

Most of the nuclear waste that was disposed of in and around Armstrong County was produced from manufacturing fuel for commercial nuclear power plants and the Navy’s nuclear submarines. Two of the multiple sites are found near my home. One is right in town by the Kiski River, and the other is found about 5 minutes out of Leechburg which is also close to my home. The Apollo one is totally cleaned up. Though, it was said to have a lot more waste than they thought. It took about 3 to 4 years to…

Radiation is defined as emission of energy in the form of x rays and gamma rays. It is transmitted from one place to another. Ionizing radiation is high energy waves that pass the body's tissue, that produces positive and negative charged particles. These high energy waves remove electrons from atoms and cause an interaction between the x rays and the patient. This process is referred to as ionizing radiation. The amount of energy acquired from ionizing radiation is absorbed into the patients…

Strontium Isotope ratios are used in archaeology to track human migration.86Sr abundance is constant, but 87Sr forms through decay of 87Rb in rock. Rock age and initial Rb/Sr ratios vary geographically, making87Sr/86Sr a location tracer. Strontium, weathered from bedrock into groundwater then taken up by flora and fauna, can substitute for Ca in tooth enamel. Enamel only forms during childhood, specifically the early first and second molars mineralize during early childhood; the third molar…
