Microwaves are an important part of our society. We use them in everyday life and its a commonly held in households, but there are negative effects to them. Microwave Radiation is lethal and you can get it from microwaves and other things in your everyday life. Over time things have been altered in order to keep people safe. Modifications have been made to microwaves in order to reduce the risk of microwave radiation.
Microwave Ovens were discovered accidentally by, Percy Spencer in 1945. He was working on an active radar set and he realized that his Mr. Goodbar was melting in his pocket. Spencer constructed a high density electromagnetic field by transferring microwave energy to a metal box using an electron tube. The first foods to be cooked in the microwave were popcorn and eggs. Once the food was placed in the box that was heated with microwave energy then the temperature of the food rose rapidly.
The idea of the microwave cooking process was patented by Raytheon in October 1945. The microwave oven was first tested in a Boston restaurant. 1947 was the first time the public were able to use the microwave oven. The first commercially available oven was also in 1947, it was built by Raytheon and it was called the Radarange. It was 5 feet and 11 inches and it weighed 750 pounds. The price of it was $5,000 and it held three kilowatts and was water cooled. The wattage is about three times more than household microwaves now.
Over time the microwave has developed in different ways. It is smaller, less wattage, and less expensive. In 1954 Raytheon produced a microwave that contained only 1.6 kilowatts. They sold it for a range of $2,000 to $3,000. In 1955 they tried to sell a 220 volt microwave but, it didn’t sell well becaus...

.... Later symptoms are loss of weight and appetite, bleeding, and discolored spots on your skin. These symptoms are more severe, and can be lethal. If you are experiencing any early symptoms or later symptoms go to your doctor.
Microwave radiation is used to treat liver cancer. It’s been tested on animals, during the process they insert an antenna into liver tissue or the hepatoma and they investigate the changes of ultrastructure,the liver pathology,and healing of radiated liver. Results showed that air bubbles were formed in liver tissue and its small veins when the temperature was higher than 80 degrees. The liver divided into three parts and the cancer was greatly reduced.
Microwave radiation is dangerous but, we are exposed to it everyday. And even though it can be lethal it is used to help us in our everyday lives and it can possibly be the cure to a cancer.
According to Helibron and Seidel (2011) nuclear medicine began as a simple experiment in the early twentieth century by George de Hevesy. De Hevesy started the experiment by deciding to test the effects of radiation on living things, beginning with bean plants, then onto furred animals, and then continued onto finding the effects of radiation on the human body, when he did this he became the first person to ever use radiation on a human being. He along with his partner E. Hofer, in 1931, consumed Deuterium which they had diluted with tea and found that traces of radioactivity stayed within their bodies for between eight to eighteen days. This was the first known use of radiation on humans (p. 1). This was just the beginning though, as time moved on the use of nuclear energy advanced and as it advanced it began to bleed into more subjects than those that it had been used in before, such as, nuclear medicine. Although it has its drawbacks, such as nuclear waste, there are many different benefits to nuclear medicine. Examples of such would be advances in therapy and treatment of disease...
Millions of people around the world use cell phones on a daily basis and people hardly realize the terminal risks. Cell phones may seem completely harmless, but they actually emit radio waves that can be hazardous towards the human body. Each time someone makes a call or receives a call, a type of cancerous radiation is given off by the cell phone in order for the user to communicate with the person on the other side of the line. Since the amount of cell phone users has rose rapidly, more people are being exposed to this kind of radiation. As cell phones undergo advancements, people are starting to use them more often, leading to an increase in the amount and length of calls each day. Some believe that these radio waves do no such harm to your body due to the radiation wave being weak but in reality, exposure to any kind of radiation is never safe. Radio waves might not affect the human body immediately, but after a long period of time the effects are bound to reveal. Cell phones can increase the risk of cancer because its radiation affects brain cells, causes tumors, and is hazardously absorbed by the tissues in the body.
One of the first inventions but more so of a discovery was the idea of nuclear fusion. It was discovered by a German scientist in february of 1939. This led to the invention of the atomic bomb. The atomic bomb was only used twice both times by the U.S. near the end of the war first on Hiroshima then on Nagasaki(Atomic Bomb).
Without this simple device, many lives would have been lost to fires. Along with smoke detectors, nuclear technology is also used in the wide world of medicine. Chemotherapy is one of the leading ways to combat cancer growth and is helping to extend the lives, and even curing, patients everywhere. While radiation in food production may at first sound like an off-putting idea, radiation is already being used to better grow the world’s farming capabilities by expanding many countries crop outputs. Nuclear technology is everywhere, and that is not a bad
...ects. For example, “Exposure to high levels of microwaves can have effects on health. Such exposure could lead to a painful burn or to the development of cataracts in the lenses of the eyes. These injuries are caused only by exposure to large amounts of microwave radiation, however, and the small amount that can leak from a microwave oven does not cause these problems” (“Radiation Exposure and Cancer”). This is why the United States formed the FCC. One of their tasks is setting guidelines and testing electronic devices, making sure consumers are not exposed to the extremes. This is why the devices in your home are relatively safe. That also includes cellphones “Neither cell phones nor cell towers have been conclusively linked to increased risks of cancer” (Radiation Exposure and Cancer). Statements like these are constantly being made after each and every experiment
...b done but can bring more side effects to the patient. Radiation is a connection to physics, which was a very important important discovery in science because it has cured many patients who have been affected by cancer when before they were left to die. Radiation therapy, like any other way exposed to radiation, can be a risk. The importance of undergoing this treatment is to see the positive side of it, not just think of the bad things that can come out of the radiation therapy. There is a risk of second cancers but isn’t it worth it? This treatment gives patients the chance to live a longer and normal life, this wasn’t an option before, so it’s important to be thankful for being born in this time period. Radiation might not be seen as a good thing in many occasions but it is now used for the good of the people affected by cancer, it’s a second chance for life.

Gamma rays can be used for many different applications, they could be of very little importance, or they could be life saving. One very important use for gamma rays is for cancer radiation therapy. Radiation therapy is a high radiation transmitted to the body to shrink tumors and kill cancer cells. The main type of radiation is using gamma rays. There are two other types; x-rays and charged particles. A machine outside of the body delivers the radiation. However in some cases it can be delivered internally through a radioactive material placed near the cancer cells. About half of all cancer patients receive some type of radiation therapy sometime, the course of their treatment.
The biological effects of radiation play a key role in today’s society and it is something that all species have to deal with on a day-to-day basis. Throughout time, this field of study has grown and has become one of the most prominent fields of science. Radiation is something that we as a human race will never be able to escape. It is naturally present and has been since planet Earth was formed. In the mid 19th Century, there were two famous scientists that are known for their exquisite contributions to the study of radioactivity. Pierre and Marie Curie were a husband-wife duo that both studied at the Sorbonne. While at Sorbonne, they studied the properties of thorium and uranium and soon stumbled upon and discovered the element polonium. Pierre then decided to study magnetism at high temperatures. Marie proceeded to study in both chemistry and physics and received Nobel Awards in both fields. She is the only person in history to do this. The “curie” is a unit of measure that scientists use to this day in radiation studies. These two were not...
The city of Berkeley passed a law that goes into the effect of cell phones. (Hill) So people are talking about how the RF waves have like a little microwave in the cell phones so they give off a little bit of radiation in the cell phones because the more you use the cell phone the more radiation you can have and when it happens to little kids because their tissue in their brain are very thin in which they can get brain tumors when using a cell phones. (Hill) He found that about 50 percent of the 326 studies showed a biological effect when the radio-frequency radiation but people found the the wireless industry he found the split was 70 - 30. (Hill) Lab studies usually expose animals to something like RF energy to see if it causes tumors or other health problems. (American Cancer Society) Researchers might also expose normal cells in a lab dish to RF energy to see if it causes the types of changes that are seen in cancer cells. (American Cancer Society) A large study now being done by the US National Toxicology Program should help address some of the questions about whether exposure to RF energy could lead to health issues. Researchers will expose large groups of lab mice and rats to RF energy for several hours a day for up to 2 years and follow (observe) the animals from birth to old
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.
All university students know the convenience and importance of the microwave. The microwave is particularly important for students living in the Towers, as this is their only kitchen appliance. Since microwaves are a staple for university students, they become dirty quickly. The best way to keep microwaves clean is to clean up spills immediately. If you can 't, however, do this, follow the steps below. Your microwave will be spotless again almost instantly.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
The microwave is a prime example of technology making us happy. If we were to get rid of the microwave, many people would be angry because it is a very helpful and time saving device. If there was no microwave people would not be able to defrost the ground meat they forgot to leave out, nor would they be able to cook a hot pocket for lunch when they were short on time. Some people believe that items that are efficient make society happy.
Heat and x-rays are an example of radiation. A type of non-ionizing radiation is radiofrequency radiation. (Cancer 1) If radiofrequency radiation is engrossed in large amounts of materials containing water and food it can produce heat. This can lead to burns, tissue damage, and harm DNA cells. Heat is the main effect of exposure to radiofrequency. (Cancer 2)
