Radiation
Have you ever been to the doctor and got an X-Ray? If so, you have just been exposed to radiation. Radiation is the emission of energy from any source. Two examples of radiation are light that comes from the sun and the heat that is constantly coming off the human body. Electromagnetic spectrum is the range of wavelengths or frequencies in which electromagnetic radiation extends. The wavelengths range from low energy (low-frequency) to high energy (high-frequency). Radiofrequency radiation stands at the lower end of the electromagnetic spectrum. It contains non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms around in a molecule or cause vibrations, but it does not have enough energy to ionize (remove charged particles such as electrons). Ionizing radiation has higher energy UV

It stands at the lower end of the electromagnetic spectrum. Some examples of this type of radiation would be power lines, microwaves, radio waves, infrared radiation, visible light, and lasers. Even though this type of radiation is less harmful than ionizing radiation, overexposure to this type can cause health problems. One example of non-ionizing radiation would be extremely low frequency (ELF). This type comes from power lines and electrical wiring. Researchers have not found a link between this type of radiation and cancer, although overexposure may have a factor in health issues. Another example is radio frequency (RF) radiation. This type comes from radios, cell phones, televisions, and microwave ovens. It can affect hearing aids and pace makers, so people need to take the appropriate measures of care when around this type of radiation. Infrared (IR) radiation and Ultraviolet (UV) radiation can cause skin cancer and cataracts if overexposure begins to occur. Non-ionizing radiation is not harmful unless there is too much exposure of it, as health problems may
For more than four years after the events of Pearl Harbor, Americans sacrificed their lives to the war against the country of Japan. The attack on Pearl Harbor on December 7,1941 achieved complete surprise and success. It was Pearl Harbor that unified American opinion and determination to see the war through on the Japanese who still maintained its position of being an aggressive enemy against Allied Powers. The U.S. fleet was rebuilt with astonishing speed, and its chain of defenses (Sakamoto). At the Potsdam Conference, a conference between the Allied forces to discuss war options, Truman learned of the successful test explosion of the atomic bomb and informed the other Allied leaders, that the atomic bomb was complete and ready. The United States, Britain, and China then issued a statement threatening to destroy Japan unless it surrendered
Radiation therapy is the utilization of radiation in order to treat diseases like cancer as well as to detect other ailments that someone may have. Since the development of radiation therapy many advancements have been made both to the process of using radiation itself, which in turn increased its effectiveness for medical use, and to the study of other possible uses for radiation. The concepts behind radiation therapy are not overly complicated, but they are still revolutionary ideas that have greatly impacted society and people’s wellness.
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation means that the rays are able to remove an electron from the atom then ions can be formed. The ions can cause damage when reacting with other atoms. Cells are able to be repaired if low dose are received. However, if cells get a high dose, the cells will be damaged or possibly die. If the cell is damaged permanently then it is referred to as a mutated cell.
Cancer has become a very common illness world wide for any age but mostly affecting adults. One can get cancer from different places in the body that is why there are so many people with cancer, because of all the different types. Cancer can affect any gender, female or male, and any age. It varies from ovarian cancer to prostate cancer, skin cancer to lukemia. Cancer has been a problem for many years yet we have not found a cure to treat and prevent cancer. If one is affected by cancer there are treatments to help take away this illness affecting their body. This essay is about a specific type of treatment for cancer, radiation therapy. There are different types of forms of particles for radiation, for example, protons and waves like x-rays and visible light. These types of radiations are grouped on how much energy they contain because it can cause different affects. A low type of energy radiation can be radio waves and heat, also known as non-ionizing radiation. Ionizing radiation has enough energy to break chemical bonds and knock electrons out of atoms, some examples of these are x-rays and ultraviolet light rays from the sun. That is why radiation is a way to treat cancer because of the strong energy it has to destroy a cancer cell, actually any cell in the body. That’s the issue with radiation therapy, is it worth the damage? It can damage any cell, wether it is healthy or cancerous, which can cause a major affect in the body later on. Although it sounds scary there are other types of treatments such as chemotherapy, targeted therapy, immunotherapy, photodynamic therapy, etc. So if radiation therapy does not sound like the best there are always other options but they do not develop the same results for radiation therapy.

After the first few days of the bombings of Hiroshima and Nagasaki Americans, without knowledge of the aftermath of these cities, began cheering and celebrating as the bombings marked the end of World War II. Also, this event showed that Americans would be the ones who would lead the world into the nuclear age. In a Gallup Poll taken from August 10-15, 1945, Americans were asked whether or not they approved or disapproved of the use of atomic bombs on Japanese cities, 85 percent approved, ten percent disapproved and five had no opinion.30 then when asked if the development of the atomic bomb was a good or bad thing, 69 percent said it was a good thing, 17 percent said it was bad, and 14 percent had no opinion (Steele).
Radiation can either be ionizing or non-ionizing depending on how the radiation itself affects matter. Non-ionizing radiation includes visible light, heat, microwaves, and radio waves. This particular type of radiation deposits energy in the materials that it passes through but cannot break molecular bonds or remove electrons from atoms. Ionizing radiation on the other hand has enough energy to break molecular bonds and displace atoms. The displaced electron creates two charged particles known as ions which can cause changes in living cells.
Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.
In order to understand the risks associated with nuclear energy, it is necessary to understand the properties of radiation and their effects. The term radiation refers to a wide range of things. Ionizing radiation is the kind that can and does cause damage. Ionizing radiation creates ions when it strikes something, which can then affect matter such as human tissue. The two main types of ionizing radiation are electromagnetic and particle. Ionizing electromagnetic radiation includes x-rays, gamma rays, and cosmic rays. Ionizing particle radiation involves alpha particles, which are helium nuclei, beta particles or electrons, and neutrons. Gamma rays, alpha particles, and beta particles are the main forms of radioactivity associated with nuclear power (Taylor, 1996).
Light is both part particle and part wave. Light is “the electromagnetic radiation that may be perceived by the human eye”. It consists of photons, which are massless bundles of concentrated electromagnetic energy. Light’s lower frequency is red, and the higher frequency is blue. Like sound, light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet, and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun, and infrared is used in night vision to see better.
We are exposed to small and non-lethal doses of radiation everyday. The type of radiation that is very lethal to humans and all other life is gamma radiation. This type of radiation, if you are exposed to it, alters the molecular structure of your DNA and can lead to mutations in your offspring and can lead to diseases like cancer. Alpha and Beta particles are usually deflected by your skin and they aren’t as harmful. Alpha, Beta and Gamma radiation are types of ionizing radiation which means they can remove the electrons in the atoms of your cells, which can cause cells to mutate. Radiation is can be useful in our everyday lives. It is used in X-ray machines to look at the bones inside your body and a lead vest is put around you to protect you from the radiation so you are not fully exposed to it.
Radiation is when the heat energy travels in actual waves. The suns energy gets to earth because of radiation. These three types of heat transfer can be easily found in the activities we have been doing the past couple of weeks having to do with a universal dwelling. They can mostly be seen when we are trying to test the heating and cooling capabilities of our universal home model.
Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field. Normal people out the world can also be exposed when coming into one of these offices and getting x-rays of some type.
Electromagnetic radiation is energy that flows through free space. Electromagnetic radiation comes in a list of energies known as the electromagnetic spectrum. Electromagnetic spectrum is the complete range of the different wavelength of electromagnetic radiation. It consists of light, radio waves, visible light, infrared waves, ultraviolet light, x-rays, microwaves and gamma rays.
Now, the three examples, Chernobyl, Fukushima, Three mile islands, show the effect of the nuclear accident. Each has different causes, but the damages were terrible.
What is radioactivity? Radioactive isotopes are heavy nuclei of certain elements having extra neutrons. The extra neutrons in their nuclei cause them to be unstable so the nuclei break up spontaneously, emitting alpha, beta and gamma radiations. For example,
