Urban decay

What can stop cancer? Cobalt-60? How nuclear medicine is helping an individual and society at large. Can you imagine that the orderly process of replacing damaged cells into new cells in your body stops? This is what happens with people who get cancer and if their treatment is not done fast, it can lead to death. Gamma knife therapy uses cobalt-60’s gamma radiation to destroy cancerous growth. In this paper, I will reflect on the research on cobalt-60 and its impact in the field of cancer,…

In conducting this experiment, the hope was to identify if there was a relationship between distance from a radioactive source and its radioactivity. Within this radiation lab experiment, we put the following hypothesis to the test: If the distance from the source, in centimeters, is increased then the Ionizing Radiation does is expected to decrease because the radiation decreases as it gets farther away from the radiation emitter, due to the loss of energy from the radioactive particles as…

pattern at the speed of light. Each photon has a certain quantity or pattern of energy. Gamma rays have the smallest length wave and their photons have the most energy of all the waves in the electromagnetic spectrum. They are generated by the decay of radioactive atoms and nuclear explosions. The high energy of gamma ray photons means they can pass through most things. Gamma rays are a form of ionising radiation, which means that when they pass through matter they pass on their energy to…

the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of long-lived radioactive element plus its decay product. Example: B) Look at the diagram below which represents the radioactive decay of uranium- 238. The shaded area represents the decay product which is lead-206. The half life of uranium-238 is 4.5 billion years, since this object has gone through two-half lives it is 9 billion years old. C) If you…

Task 1: radioactive decay is a nuclei of some isotopes which are unstable. If a radioactive isotope decays the it will change and become a different atom with different number of protons. Radioactive decays also are a process which has an unstable atomic nucleus and which causes it to lose energy this because of radiation, for example there three main types of radioactive decay alpha, beta, and gamma particle. If a material has unstable nuclei it would be considered as radioactive. If an atom…

Method In this LAB we measured how long it would take for varying starting amounts of M&M’s to decay. We did this LAB in order to find out if the rate of decay is dependent upon the initial amount of mass present in a radioactive sample. We changed the starting number of M&Ms or the initial “mass” of the M&Ms (our independent variable) in order to be able to come with a clear answer to the question. We also controlled the number of times we would shake the cup in order to not change the way we…

Nuclear Regulatory Commission, 2014). The dirty bomb is deliberately constructed to cause trepidation in heavily populated urban areas that could generate more fatalities than the IED or the radiation it disseminates (REMM, 2016). Radiological Dispersion may cause disquiet in citizens who think they are being, or have been exposed to radiation (The U.S. Nuclear Regulatory Commission…

Exposure to ionizing radiation can happen internally or externally. Internal exposure may result by “inhalation, ingestion or through the bloodstream”. External exposure can transpire by breathing in “airborne radioactive Material”. Other external sources to ionizing radiation are cause by medical radiation through the imaging department. This medical procedures include x-rays for diagnosing and treatment, and even research. Gamma rays are also use by medical doctors to create radioactive…

The discoveries of radioactivity, radium, and polonium offered new medical theories to improve the quality of living in society. After studying radium and polonium, Alexander Graham Bell observed that the two elements might help in treating tumors and other forms of cancer. Based on Bell’s theory that radium and polonium might aid in therapeutic methods, physicians began testing the effects of the new elements in humans. Pioneering the experiments on human subjects in the field of nuclear…

Radiation is often seen by individuals as a substance that is rare and uncommon. Others believe that it only comes from nuclear bombs. However, that isn’t the case. It is found in everything from the soils that people walk on every day, to the walls and floors inside their homes. There’s radiation found in food and water that are consumed by people on a day-to-day basis. It is found within the gases inside the Earth’s atmosphere, and from cosmic rays from space ("Radiation in Everyday Life").…
