6. Describe the way in which the above named industrial and medical radioisotopes are used and explain their use in terms of their chemical properties. Cobalt-60 is used in industrial radiography to inspect metal parts and welds for defects. Beams of radiation are directed at the object to be checked from a sealed source of Co-60. Radiographic film on the opposite side of the source is exposed when it is struck by radiation passing through the objects being tested.
Industrial uses include testing of welds and castings, and a large variety of measurement and test instruments including levelling devices and thickness gauges. It is also used to sterilize instruments, and to irradiate food to kill microbes and prevent spoilage. But although having all these uses, it’s mainly used in industrial radiography helping to detect these welds, cracks and or little holes in pressurized piping. The radiation is used to detect any faults in a surface through various ways, a popular scheme is known as the panoramic structure, this is when the radioactive isotope (cobalt – 60) is placed in the centre of a room, and then depending on the radiographer, film cassette will be placed in a specified location to check for leaks and cracks. As the cobalt – 60 emits gamma rays that are easily stopped, the cassette will only reveal a change in colour where gamma rays strike sensitive silver halide ions but the cobalt will not pass through the walls hence revealing cracks or small holes.
It can actually heat the lead used in the older models. This could cause cardiac tissue damage in patients. The lead acts as a conductor to the radio frequency energy. The studies have shown a wide range in heating after an MRI. (Ahmed, et al., 2013) The gradient magnetic field comes about by the actual process of the MRI.
What type of incident involves an unusually wide distribution of a disease or simultaneous outbreaks of a disease? (1 point) A. Biological B. Chemical C. Incendiary D. Nuclear 4. What are three primary techniques for minimizing exposure to radiation and radioactive materials?
Additionally, the uranium used in nuclear reactors undergoes an enrichment process to prepare it, but additional enrichment can generate weapons grade uranium. According to the The Nuclear Age Peace Foundation, the enrichment process is openly shared between nations. In addition to those risks, as nuclear technologies become more widespread the risks of accidental contamination of people and the environment
Methylene chloride: ethanol (1:1 solution) What solvent system will you be using to "develop" your TLC plates in the TLC of Analgesics lab? ethyl acetate with 0.5% solution of acetic acid How will you be visualizing your TLC plates in the TLC of Analgesics Lab? an UV lamp or a UV light What is the name of the hydrogenation catalyst used in the Hydrogenation of Olive Oil Lab? 10% Palladium on
By having helium-3 as the next power production on earth it will also decrease the amount of pollution and radioactive waste in the atmosphere. Nuclear power which involves the process of fission has provided
The toxic waste can be managed by treating it well and burying it underground. Also new technology has made it possible to run Nuclear Power plants with thorium. To use thorium the Nuclear Power Plant needs to be driven on the Accelerator Driven System. This system may have a large price tag but it will pay itself back within fifty years or so. Thorium compared to Uranium creates less toxic waste and also unlike Plutonium (the by-product of uranium) the toxic waste created by Thorium will only takes 500 years to be declared safe.
(Brand, 2010) Since hydroelectric power in most places is maxed out, coal and nuclear power will be discussed in this essay. There are a lot of debates about which one of the energy sources is superior to the other, which is less harmful to the environment, easier to build, cheaper and more convenient in general. The conclusion will elaborate on the differences and the similarities that these to energy sources have. The main thing that we are looking at when talking about these energy sources is what does it do to our environment? What happens to the waste?
(Delgado 43) Research in atomic energy progressed when scientists learned that using a neutron to bombard atoms performed better than protons and alpha particles. That process would later become known as fission. Later into the research, two radio chemists, Otto Hahn and Fritz Strassmann would pioneer that the result of the splitting an atom concluded in lighter elements. They
