Electric Magnetic Fields
Homes are filled with electric magnetic fields (EMFs), EMFs
are created every time anything electrical is used. Hair dryers, alarm
clocks, micro waves and radios are just a few examples. All these
appliances cause leukemia, a form of cancer.
High EMF fields are not very unusual. EMFs can
pass through walls, so one can also be exposed to them from power
lines and transformers. Using a hair dryer for 3 minutes would give
the same exposure that one would get living next to a high voltage
power line.
Just in the last 18 years health researchers found out that EMFs
are dangerous. That is why this is such a new topic.
In 1979, two scientist found a connection between electrical
systems and childhood cancer (leukemia). This then set off more
studies on this topic around the world. They found in their research
that children who lived near power lines were at three times the risk of
contracting leukemia, than children who did not live close to the lines.
A later test concluded that the risk of living near a high voltage line
doubled the chances of getting cancer. This test was conducted by the National Cancer Institute (NCI), it also showed that electrical workers are at three times the risk of contracting cancer.
The NCI test was different in many ways from the first test.624 children were used in the study, The strength of the magnetic fields were measured with a device that was placed underneath the child’s bed. The NCI also measured the nearby power lines EMF levels. The people collecting the data did not know if they were collecting data from patent or the control. All the investigators were neutral meaning that they did not care one way or another.
EMF exposure can be reduced by standing farther away from
electrical appliances. If possible stand 3-5 feet away from
I think the chapter that helps to support her main point the most is chapter four titled “Space.” In this chapter, she discussed a great deal about the geographic distribution of cancer as well as the environment of the people who are more likely to get cancer. This includes: job type, living location, and living surroundings. To expand on each, she states that workers with
One of the biggest problems with working in a mine is the the health risks you are taking when stepping into a mine and staying there anywhere from 10-16 hours of the day. Miners of the Gilded Age, needless to say, did not live very long at all. Some of the diseases they contracted were black lung, Silicosis, and COPD. Coal Miner’s Pneumoconiosis, more commonly referred to as Black Lung, is caused by inhaling respirable coal mine dust. Silicosis is a more specific, but yet still commonly found in coal miners, version of Black Lung caused by inhaling respirable crystalline silica, such as Quartz, a major component in rocks. Chronic obstructive pulmonary disorder, or COPD, is still common today in people who don’t even work in mines. COPD is a progressive disease that increases airway
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
5). The high mortality rates are related to the environmental exposures of the coal mining along with other factors such as smoking, poverty, education, age, race and sex. “Higher lung cancer incidence and mortality in the Kentucky Appalachia is thought to result from higher smoking rates and correlates of poor socioeconomic conditions which limits the population access to health care” (Hendryx, O'Donnell, & Horn, 2008, p. 2). The population residing in coal mining areas, are exposed to contaminated water and air from the coal mining and there is a concern for respiratory illnesses related to the pollutants. The fumes or toxin released from the coal mine, this places the individual at a risk for respiratory issues such as emphysema, black lung, brown lung and
The major encounters that Tesla and Faraday faced included social, economic, intellectual barriers. Considering socially, Faraday was considered to be a “...high-priest of Nature, revealing the hidden forces...”(Shortland) People saw Faraday as the highest of his field, the one who was the closest to God in relation to understanding his creation. This also shows the social standard at this point in time, many going to church and understanding when someone references a religious point. Also, for social encounters, we have Tesla with his description f what the future will be like. This was not a reaction to the society that Tesla was around, but a prediction of what they were to become. Tesla, hoping to see that people would grow to become stronger
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.
Your chance of getting cancer from exposure to a chemical, however, like your chance of being killed in a vehicle accident, is not as easy to understand. This is because conditions that affect your chance are always changing. In the case of a vehicle accident, the road may be slippery, you or another driver may be drunk, your car or another vehicle may get a blow out at high speed, someone may fall asleep at the wheel, someone may throw a rock from an overpass, or an airplane may fall from the sky. All of these conditions and many more affect the chance of being involved in an accident. Sometimes you can control the conditions effectively, but most of the time you can't.
When someone works in an environment where they are exposed to chemicals, dust, fumes and molds, they are more likely to develop asthma. Along with asthma, constant exposure to chemicals and vapors can cause serious lung problems that can develop into more serious lung problems.

Likewise, lung cancer affects people who have never smoked due to the presence of radon and household pollutants. Radon has contributed to 10% of all lung cancer deaths and is considered second to smoking. There is no way to predict who will get cancer, but inherited genetic risk factors make some people more vulnerable to carcinogenic exposures than others. Lung cancer starts whenever there is an uncontrolled growth of abnormal tissue cells that affect the normal function within the lungs. As these abnormal cells grow they form tumors which can block the oxygen exchange within the body. (Lungcancer.org, 2014).
Smoking is leading cause of lung cancer. Smoking causes more than 80% of lung cancer cases. When you smoke you are taking in more that 4,000 different chemicals, which are all proven to be cancerous. Even if you do not smoke you are still at risk for getting lung cancer. Second hand smoke is just as bad as smoking itself. Each of the harmful chemicals can still enter into non-smokers lungs when they are around smokers. Radon is also a leading cause of cancer. Radon is a radioactive gas that is invisible and odorless. Radon can be found in the surface of the earth. When people come in contact with radon it cause the same results as smoking, the cells be come usual. Thus leads to lung cancer. People can also come in contact with carcinogens while they are at work. Many cancer-causing chemicals can be found in the work place such as asbestos, uranium, arsenic, and petroleum. If you are exposed to these carcinogens for long periods of time, just like smoking or radon, you will develop lung cancer.
Smoking cigarettes is the causes to 90% of lung cancer patients in the U.S. There are about 7,000 different chemicals in cigarettes and most of them are poisonous. About 70 chemicals can definitely cause cancer in both animals and people. Secondhand smoke can also cause of lung cancer and about 7,300 people die every year. Radon also causes lung cancer. Radon is a gas that is found in rocks. In the United States about one out of 15 houses have high levels of radon. The food you eat can play a role in the chances of you developing lung cancer. Lung cancer can also be expected if your family has a history of it.
Brain cancer can be caused by many things. Environmental risk factors are a major cause of brain cancer in many patients. Some of the occupational factors include oil refinery workers, chemists, and rubber-industry workers. Reason for these occupational risk factors is inhaling possible carcinogenic vapors. Other causes that have been suggested (not proven) include smoking, radiation exposure and HIV. Heredity however has not been proven to be a cause. Also, the World Health Organization has classified mobile cell phone use as a possible cause for brain cancer.
The Earth’s magnetic field is a major component to exploring the earth. The north and the south poles have always been a guide for travelers. Using compasses, the direction of the north pole and the south pole has always been provided by the magnetic force of the magnetic field. What many people do not know though is the earth’s magnetic field provides way more than that. The magnetic field, also known as the magnetosphere, protects us from all kinds of harmful substances. Some of these substances include solar wind and harmful radiation from the sun. The magnetosphere also protects the atmosphere, which protects us.
Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
