Ionizing radiation

Nuclear radiation effects ERT term 4 With the depletion of fossil fuels and their harmful carbon dioxide emission, nuclear power is an increasing energy source. World-wide around 11.5% of energy is nuclear and in countries like France it’s 76.9% of their power source. With nuclear power being a renewable and relatively clean source of energy, nuclear power plants are being built all over the world. But despite the environmentally friendly aspects of nuclear power, when nuclear waste is not…

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, its impact on society and its pros and cons. “Cobalt was discovered in 1735 by a Swedish scientist named George…

cancer, which uses forms of radiation. It uses high-energy rays to treat disease and it works by destroying cancer cells in the area that's being treated. With external radiotherapy a carefully controlled beam of radiation targets the area where the cancer cells are found. A team of radiation therapists, cancer specialists and physicists try to work out the best way to target the cancer whilst minimising the damage to other tissue. For curing cancer the radiation needs to be very carefully…

There are nerve cells running through the entire length of the body and this includes the organs. Have you ever thought why you are not experiencing any forms of pain, when you are stretching? The internal organs, primarily the lungs are rubbing against the chest cavity, and yet you are never experiencing any form of pain. The same can be applied when you are breathing heavily. We are not experiencing pain because almost all the major organs and cavities within the body are lined by mesothelium.…

doing this experiment. First thing is how strong is the radiation based on the distance from the source and if thickness of the material effects how much radiation gets through. Introduction-One thing to know about this experiment is Isotopes.Isotopes of an element are different versions with same number of neutrons but different number of neutrons. Also these isotopes can be unstable which means they decay overtime releasing radiation. Radiation is the what we are going to look at while doing…

How a Geiger counter works is when Radiation is moving around randomly or coming out of a tested radioactive substance outside the detector tube, the radiation enters the gap on the end of the tube. When the radioactive nuclei and the inert gas molecules(this is found in the tube) bump into each other it causes ionization, some of the gas molecules are turned into positive ions and electrons, the positive ions are attracted to the outside of the tube. The electrons are attracted to a metal wire…

The Physics of PET Scans All elements are composed of atoms, which are composed of small particles called protons, neutrons, and electrons. The nucleus of an atom is made of a tightly packed collection of protons and neutrons. You would think that with positively charged protons being packed so closely together the nucleus would fall apart, however this is not the case. There is an attractive force called the “nuclear force” which is able to overcome the repulsive force of the adjacent…

created when a component is attacked with high energy electron. So when a high energy electron attacks the target electron in an atom it, this leads to the target electron being ejected from the inner shell of the atom. Whereas bremsstrahlung radiation is when radiation is given off by a particle that is charged, usually an electron, because of acceleration which is caused by another charged particle, usually an atomic nucleus. The x ray beam from an x ray is modified to suit the needs The…

senior project, I focused on the issue of radiation exposure radiologic technologist face with their jobs. I described how radiation is dangerous when used too much and what health issues can arise from that. I also explained the safety procedures used while radiation is being administered and the regulations set in place to keep the technicians and patients safe. I created an informational brochure to inform future radiologic technologists the dangers of radiation exposure and how to stay safe…

The toxin Radon is a natural radioactive gas that is odorless and tasteless. It is really helpful with cancer therapy. It was initially used in hospitals to treat tumors and to help cure the illness. Radon has a half life of around four days, meaning half of any given amount of radon can decay other products for four days. Other parts of Radon is produced in the soil and gets exposed in the air. It moves from the soil to groundwater, which can be harmful because it gets into our drinking water.…
