Abstract
Discusses an experiment of the shielding of radiation. The experiment uses fluid flow measurements and the method of continuous flow to determine the coefficient of viscosity. Includes the calculations and results of the said experiment as well as diagrams. Discusses the conclusions and several human errors that happened when carrying out the experiment.
From the Paper
"There are two different ways water can flow this can be either streamline or turbulent. When a liquid has a streamline its particles flow in regular and smooth paths called streamlines. In this type of motion the viscous drag opposing the flow is proportional to the average velocity of the liquid. In turbulent flow, the particles have irregular motion therefore the viscous drag is proportional to the square of the velocity. "

Abstract
This paper explains that it is next to impossible to avoid sources of natural radiation in our everyday life, but precautions can be taken to maintain distance from local sources of radiation and to use distance, time, and radiation-shielding as protection. The author points out that radiation is not responsible for the assumed mechanism of carcinogenesis caused by the exposure to magnetic fields. The paper relates that the nuclear industry and many other sources of radioactivity are used in an enormous range of industrial processes, such as industrial radiography, thickness gauges, smoke alarms, and medical diagnosis and treatment.

From the Paper
"Ionising radiation does not accumulate in our body, but science proves that the radiation effects are evident from exposure to large amounts of radiation, as in sunburns from too much exposure to strong sunlight. Radiation carries energy that has a damaging effect on the living cells of living things and can either kill them or change their structure and function to inhibit correct functioning but this would take large doses to kill a good number of cells to cause death. Radiation dose would have to be several thousand times bigger than the dose received annually from the environment to cause death. Death would occur if the person were exposed more over a year. For example, exposure to sunlight over a year gives one a suntan, but one-day exposure of sunbaking could cause death by sunstroke."

From the Paper
" Introduction
This research examines the concept that "all radiation is dangerous" from three perspectives: as a matter of scientific fact or truth, as a policy basis for radiation protection programs, and as a warning for everyday precaution among a general public. Beyond differences in radiation types, substantial differences in the sciences can be invoked to consider the truth of a question. The bulk of this work is addressed to biophysics, agriculture, and medicine. The premises will be considered as follows: Is there any benefit (as opposed to danger) that can result from any level of irradiation?; Can there be a threshold level of radiation of any kind above zero below which no deleterious effects will be manifested among plants, animals, or minerals?

Abstract
The paper deals with small cell lung cancer and the problem with regard to radiation and memory loss. The paper states that this form of cancer is prone to brain metastases. The paper confirms that prophylactic cranial irradiation is a controversial method of radiation that has shown to have positive outcomes in small cell lung cancer patients. However, little is known about the effects of radiation on the brain and especially on long-term cognitive and memory loss. The paper, in referring to various studies, concludes that the research is compounded by the large number of variables that need to be taken into account in ascertaining the effects of the process of radiation.

Summation and Conclusion
From the Paper
" Lung cancer is one of the most prevalent forms of cancer that affects both men and women in the United States and the world. As figure 1 above illustrates, the number of deaths from lung cancer in the United States far exceeds other common forms of cancer. There are numerous statistics that indicate the increased risks of lung cancer and small cell lung cancer. Figure 2 below illustrates a projection of morality rates in various countries over a ten your period of time. This again clearly indicates the importance of research into lung cancer and particularly the more severe form of small cell lung cancer."

Dental Radiation, 2008.
A discussion on whether radiation is safe in dental offices.

Abstract
The purpose of this research paper is to answer the question: "Is radiation safe in the dental office?" It hypothesizes that despite predominate thinking by dentists, cumulative radiation over time, even exposure to dental radiation in small amounts, can lead to health problems and significant health and safety issues for the patient and for personnel working in the dental office. This is especially true of women during their child bearing years. It also investigates whether information or empirical studies exist that quantify the amount of radiation people are exposed to for dental procedures and whether this level is safe to the patient or the people that may be around or inside of the room where the radiation is occurring.
Outline:
Introduction
Analysis of Dental Practices
Conclusion
From the Paper
"The proposition or purpose of radiography in the dental office is to provide dentists with diagnostic information about the bones in the mouth or teeth, while keeping radiation levels as low as possible. Dentists claim that X-ray examinations are ordinary examinations performed in the office with the purpose of maintaining a patient's dental care. There is evidence however that cumulative X-ray exposure may prove detrimental, so why would dentists continue to use it? I propose the use or over use of X-rays is partly a result of the lack of information about the cumulative effects of dental radiation. Dentists are as ignorant as patients in many cases when it comes to the safety of radiological exams. Most are likely taught at the university level that X-rays should be done annually or as often as necessary to promote proper health and detect early damage to the teeth."

Abstract
This paper explains that, for several decades, the medical community has alerted the public to the incidence of birth defects that are directly related to radiation, underscoring the long-term impact that exposure to radiation has on the body and on future offspring. The author points out that exposure before conception carries a risk of specific birth defects including mental retardation and childhood cancers. The paper stresses that to avoid these risks in the future it is important to re-evaluate the location of nuclear reactor sites as well as the frequency of x-rays.

From the Paper
"A defect occurs when there are changes in the DNA. Changes can occur spontaneously or can be caused by an external factor. One of the external factors that have been strongly linked with changes in the elements of DNA is exposure to radiation. Changes that are caused or directly linked to the exposure to radiation are referred to as mutations.
When these changes result from radiation exposure they are called radiation-induced mutations."

Abstract
This paper discusses the many positive aspects of UV radiation. The author examines the way ultraviolet light is commonly used, defines UV light, its dangers and how it's used in fluorescent lighting. The paper also describes how UV radiation is frequently used in water purification plants, destroying harmful bacteria.
From the Paper
"UV radiation is what is responsible for causing human skin to tan. Unlike x rays, ultraviolet radiation has a low power of penetration, so its only direct effects on the human body occur on the skin?s surface and include sunburn, suntan, aging, and carcinogenic changes. Most of us know that ?sunburn? is not simply a metaphor but is in fact like burns from other forms of radiation and can include symptoms ranging from redness and tenderness to blisters, swelling, seepage of fluid, and sloughing of the outer skin. Tanning ? while it is never healthy, as we know now, is simply a natural body defense that uses melanin to help protect the skin from further injury from UV radiation."

From the Paper
"Even though cell phones and fortune cookies may not initially appear to have a common thread, the concept that connects them is that those who market cell phones, in a similar sense, do not usually consider what happens to those who purchase and use cell phones. In the study completed by Salford et al funded by a grant from the Swedish Council for Work Life Research. Completed during 2002, the authors examine potential risks of radio-frequency electromagnetic fields for the human body. Their previous studies posit ". . . weak pulsed microwaves give rise to a significant leakage of albumin through the blood-brain barrier."

Abstract
This paper describes some of the horrific radiation experiments the U.S. government performed on members of its Armed Forces, private civilians, and animals in the name of research and science. The paper asserts that the government was not ignorant as to the effects of these experiments and that it continues to perform different, but equally hazardous, experiments on military personnel, as evidenced by the high rate of unexplained illnesses and diseases in soldiers returning from their tours of duty overseas.
From the Paper
"Today it seems almost inconceivable --if not patently paranoid-- to think that less than fifty years ago Americans would have sat passively by while the government tested high levels of radiation on the captive population. Would we have really bought a line saying that it was safe to be downwind of nuclear explosions? Would we really have put up with government sponsored radiation tests run on the most vulnerable members of society? Unfortunately, the answer is yes. Despite the fact that even back then any cautious look at the evidence would have demonstrated the risks of radiation, the very people with whom we entrust our daily survival -- doctors, scientists, and the elected government itself -- intentionally deceived the American public about the risks of radioactivity and the exposure rates which they would be experiencing."

Abstract
This paper describes the nuclear explosions conducted by the U.S. Department of Defense on the Marshall Islands from June 30, 1946 until August 18, 1958. The paper looks at the damage caused by the testing, the media's involvement in exposing the damage and how the U.S. responded to legal actions brought against the U.S. government by Marshallese living on the islands at the time of the nuclear explosions.
From the Paper
"From June 30, 1946 until August 18, 1958, the United States Government conducted a total of 67 nuclear explosions off the Marshall Islands, "all of which were considered atmospheric" (Republic of the Marshall Islands 1). The most horrific of these blasts was the 'Bravo Shot,' conducted in the Bikini Atoll on March, 1954. This blast was as powerful as 1000 hydrogen bombs (1) and much more devastating than the 1945 Hiroshima blast. However, the full extent of the destruction was clouded by governmental reticence for years, due to Cold War defense secrecy."

From the Paper
"Evolution is a process of change and development as organisms adapt to their environment and to changing circumstance through time. A variety of mechanisms have been identified as being involved in the process of evolution. This process does not take place in a steady and even manner, and eras of massive change have been identified in the fossil record during which a process called radiation has taken place, producing many new species and so many changes in a given population. Such a sudden and massive expansion of species has been identified in different parts of the world, such as the rapid growth in diversity of cichild fish in Lake Victoria in eastern Africa, where more than 500 species have evolved over the last 12,000 years. Scientists have sought to discover why such radiations occur.
Darwin explained the process of specialization and related..."

"Solar Radiation and the Atmousphere
As the earth's nearest star, the sun determines much of what happens on the earth--its energy is what allows continued life on the earth, and its actions create the earth's weather, in the form of wind, clouds, and other climatic examples. The sun's warmth and energy are so important that without them the earth would become encased in ice (1:74). However, the earth is not completely open to solar radiation. The different layers of the earth's atmosphere provide different interactions (and different results from those interactions) with solar radiation.
The earth's atmosphere, the receiving end of the sun's radiation, is divided into four parts: the troposphere, which is the bottom-most layer and extends from the earth's surface to about 11 kilometers high (at which point the stratosphere..."
