Nuclear energy has, for some time, been a controversial issue. With incidents like that of Chernobyl, Three Mile Island, and the more recent complications caused by the earthquake and tsunami Fukushima reactors in Japan, concern about the safety of nuclear energy has become a major issue. A lot of this concern probably exists because of a lack of information and education about both radiation and its effects. It is my belief that nuclear power is no less safe than any other form of energy generation, and can produce significant amounts of power.
Very few people truly understand how radiation works, or even what it means. When most people use radiation, they usually mean ionizing radiation, the kind of radiation that causes electrons to leave the atom, thusly ionizing it. Ionizing radiation, like ultraviolet rays from the sun, or x-rays, is harmful, non-ionizing radiation is not. Some examples of non-ionizing radiation are visible light (the light one can see from the sun, or a fire, for example) or FM radio waves. While ionizing radiation is considered harmful, it is necessary to understand the concentration in which these are harmful.
Even now, there is no clear consensus on when the negative effects of radiation start to occur. There are arguments that even the smallest amounts of radiation increase one’s risk of suffering negative effects, with others arguing that one needs a certain level of exposure before the risk of negative effects even has the possibility of occurring. To use an example, does smoking just one cigarette give someone a chance to develop cancer? Or does the exposure have to be greater, something like a pack a week, to even begin to have a chance of getting cancer? The answer to this is not easily determina...

Nuclear power is a growing source of energy to most of the world for many benefits. People doubt the significant of nuclear power because of one accident. Due to this accident, the world has only seen the flaws in nuclear power and not the many benefits it has to offer. Nuclear power would benefit worldwide if people would let go of the past and look towards the future. Nuclear power is a better alternative energy because of its economic and environmental benefits.
In my opinion nuclear power is pretty amazing, and I doubt that people really believe otherwise. The amount of energy that it can produce compared to other sources of energy is huge. I believe that as long as it is done with the utmost care, nuclear power is the best source of energy we can
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
After the United States developed the atomic at the end of World War II, interest in nuclear technology increased exponentially. People soon realized that nuclear technology could be used for electricity, as another alternative to fossil fuels. Today, nuclear power has its place in the world, but there is still a lot of controversy over the use of nuclear energy. Things such as the containment of radiation and few nuclear power plant accidents have given nuclear power a bad image. However, nuclear power is a reliable source of energy because it has no carbon emissions, energy is available at any time, little fuel is needed for a lot of energy, and as time goes on, it is becoming safer and safer.
Radiation is something that the naked eye cannot see, yet has the potential to save lives one treatment at a time or even one image at a time. Since the discovery of x-rays in 1895, it has branched out into numerous modalities each independently specializing in their own ways. X rays are used to aid in the diagnosis and treatments of patients on a case by case scenario. Sometimes doctors can make a diagnosis on the same day or conclude that a patient will require radiation therapy within weeks to follow. Whatever it may be, the importance of x rays and radiation itself is a crucial part of the medical field when it comes to saving lives. Initially it all started with the discovery of x rays but then three years later radiation therapy was introduced to aid with
There are ways to better understand how radiation affects the body when compared to other every day activities. If an occupational worker receives 1 rem per year then is it possible that 51 days is expected to be lost. A person that smokes 20 cigarettes a day takes about 6 years off of their life. People that are overweight by 15% take about 2 years off of their life. In actuality radiation would seem as though it is not any more harmful than other everyday activities people decide to do such as smoke, chew tobacco, or sky dive. The risk of taking days, weeks, years off of ones lives will always be present depending on the activity they choose to be part of. However, radiation exposure in the healthcare field is used to extend the patient’s life by helping them find out what is going on in their body. A patient that comes in with RLQ pain, nausea, and vomiting then an abdomen x-r...
If ionizing radiation passes through a cell in the body, it can lead to mutations (changes) in the cell’s DNA, the part of the cell that contains its genes (blueprints). Sometimes this causes the cell to die, but sometimes it can lead to cancer later on. The amount of damage caused in the cell is related to the dose of radiation it receives. The damage takes place in only a fraction of a second, but other changes such as the beginning of cancer may take years to
The world is facing an energy crisis and many are unaware of this growing problem. Sustainability is avoiding depletion of our natural resources in order to provide for future generations, and the only way to ensure that resources are available into the future is to find alternative sources to meet the world’s energy needs. Nuclear energy is just one source of alternative energy being implemented today in an effort to support the needs of the population and mitigate global climate change. Nuclear energy holds the necessary benefits in order to continue being used globally as an alternative solution.
Media coverage of such cases have made the public less comfortable with the idea of moving further towards nuclear power and they only opt for reducing human activities to reduce global warming. It is true that there have been some notable disasters involving nuclear power, but compared to other power systems, nuclear power has an impressive track record. First, it is less harmful and second, it will be able to cater for the growing world population. Nuclear power produces clean energy and it delivers it at a cost that is competitive in the energy market (Patterson). According to the US Energy Information Administration, there are currently 65 such plants in the Unite States (National Research Council). They produce 19 percent of the total US energy generation.
Radiation exposure can affect children as well an children have the risk of being the most harmfully effected by radiation because their body absorbs substances differently also their bodies can or are more likely to get certain kinds of cancers from too much exposure, “they are also closer to the ground, where radioactive fallouts settle.”
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need for energy in today’s current world, exploring different ways of producing power is necessary. The differences and similarities between nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production. To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”).
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
The greatest disadvantages of nuclear energy are the risks posed to mankind and the environment by radioactive materials. ‘On average a nuclear plant annually generates 20 metric tons of used nuclear fuel cla...
