Background radiation

So removing coal isn’t an option, at least not without a gradual process and well thought out plan. Even then, coal mining creates jobs. Over 174,000 jobs are created by coal in the United States, and this number does not include jobs that are indirectly made possible which is in the tens of thousands. This information can be found on Sourcewatch’s article titled “Coal and Jobs in the United States”. And with the addition of scrubbers making coal a very clean process, why should we remove it?…

carbon emission? Hypothesis: If the Earth's concentration of carbon is high, than there will also be an increase in the Earth’s land temperature because of greenhouse gases that are created over time resulting in the warm up the earth’s land. Background Information: The earth is kept warmer than it should be because of greenhouse gases in the atmosphere. They retain heat. One of the greenhouse gases that have the biggest effect is Carbon dioxide which is released into that atmosphere…

calculus and periodontal diseases. Radiographs take a big role in dentistry. As a student graduating as a dental assistant I have notice and experienced with patients that patients question the fact why they are getting x-rays and if the dose of radiation they are being exposed to is bad. Studies have shown that the exposure in dental x-rays is very low and still many patients doubt on those studies and refuse to get x-rays done. Radiology in general is tough, as…

because most of what I learned had nothing to do with actually being a radiation therapist. I know it was only the first week, but I thought I would learn more. Coming into this week I thought I would be doing more with the therapists, but I spent most my week with the nurses and doctors. I learned a lot from them about what happens throughout the rest of the department, and I think what I learned really helped give me a good background on what patients all go through. It was a little…

The Marble Institute of America notes, “There are many sources of radiation in a typical home. Common items such as concrete blocks, televisions, smoke detectors — and even Brazil nuts, bananas and potatoes release measureable levels of radiation. The fact is radiation and radon levels from other sources in the home are far more significant than what may be measured from granite countertops.” The Environmental Protection…

gives the three sources to create nuclear energy: fission, fusion, and radioactive decay. Farther into book Ferguson gives background information on nuclear energy and the health risks that can develop from it. People exposed to too much ionizing radiation over long periods of time are at a higher risk for developing cancer; however, the human body can fight off ionizing radiation in low dosages, so containing the amount of…

- known as Big Bang nucleosynthesis. A second assertion concerning the Big Bang I scanned over, would explain cosmic microwave background radiation. Believing that the universe came from a hot explosion would explain the radiation that exists; the radiation is remnant heat created from the hot explosion. The explosion would create high energy atoms, generating radiation. A third assertion supported the Big Bang to as why the cosmos is cold. The claim said that as the universe was expanding, the…

by showing that almost all the galaxies are red shifted, meaning that they are moving away from us. Describe the probable origins of the Universe including the transformation of radiation into matter which follow the Big Bang The Universe started with a Big Bang. At the beginning of the Big bang, there was only radiation. However over time ranging from 300 seconds to 1 million years, the particles combined to form atoms…

Abstract: The purpose of this lab was to show the different absorption and emission rates of three different substances. Radiation laws, albedo, and specific heat are all reasons why this is achievable. An agreed upon hypothesis is that the sand will absorb the most heat due to the number of molecules, the moss will absorb the second most because it doesn't have as many molecules as sand, but it has more than water, which isn’t as complex. To complete this experiment, you need three beakers of…

ozone in the stratosphere protects us from the harmful ultraviolet radiation and absorbs heat from the infra-red radiation. Reducing the amount of ozone probably causes irreversible and permanent damages to human and environment, especially in Antarctica and South Hemisphere countries. This essay examines the consequences of ozone depletion to human health, climate and ecosystems before making discussion and conclusion. Background Scientists and scholars have started to measure the concentration…
