Map of Natural Radioactivity

Many people do not realize that radioactivity occurs naturally on Earth. In fact, it is actually quite common and can be found virtually all around us in the rocks, soil and air. Natural radioactivity maps may look quite similar to normal geologic maps. Different types of rocks have specific levels of uranium and radon, so scientists often have a good idea of the levels based on geologic maps  alone.   In general, a higher altitude means a higher level of natural radiation from cosmic rays. Cosmic radiation occurs from the suns solar flares, as well as subatomic particles from outer space. These particles react with elements in the Earths atmosphere as they come into contact with it. When you fly in an airplane, you actually experience significantly higher levels of cosmic radiation than from being on the ground.   People experience different levels of natural radioactivity based on their geographic locale. The geography and topography of the United States is very diverse, and as you may expect, levels of natural radioactivity differ from region to region. While this terrestrial radiation should not concern you too much, it is good to be aware of its concentration in your area.   The featured map was derived from radioactivity measurements using sensitive instruments. The following explanatory text from the US Geological Survey  highlights a few of the areas on this map that show especially high or low levels of uranium concentration. Radioactive Areas of Note Great Salt Lake: Water absorbs gamma rays so it shows as no data area on the map.Nebraska Sand Hills: Wind has separated the lighter quartz from the clay and heavier minerals that usually contain uranium.The Black Hills: A core of granites and metamorphic rocks high in radioactivity is surrounded by less radioactive sedimentary rocks and gives a distinctive pattern.Pleistocene glacial deposits: The area has low surface radioactivity, but uranium occurs just below the surface. Thus it has a high radon potential.Deposits of glacial Lake Agassiz: Clay and silt from a prehistoric glacial lake have higher radioactivity than glacial drift surrounding it.Ohio Shale: Uranium-bearing black shale with a narrow outcrop zone was scooped up and spread over a large area in west-central Ohio by glaciers.Reading Prong: Uranium-rich metamorphic rocks and numerous fault zones produce high radon in indoor air and in ground water.Appalachian Mountains: Granites contain elevated uranium, particularly in fault zones. Black shales and soils above limestone also contain moderate to high levels of uranium.Chattanooga and New Albany Shales: Uranium-bearing black shales in Ohio, Kentucky, and Indiana have a distinctive outcrop pattern clearly defined by radioactivity.Outer Atlantic and Gulf Coastal Plain: This area of unconsolidated sands, silts, and clays has one of the lowest radon potentials in the United States.Phosphatic rocks, Florida: These rocks are high in phosphate and associated uranium.Inner Gulf Coastal Plain: This area of the Inner Coastal Plain has sands containing glauconite, a mineral high in uranium.Rocky Mountains: Granites and metamorphic rocks in these ranges contain more uranium than sedimentary rocks to the east, resulting in high radon in indoor air and in ground water.Basin and Range: Granitic and volcanic rocks in the ranges, alternating with basins filled with alluvium shed from the ranges, give this area a generally high radioactivity.Sierra Nevada: Granites c ontaining high uranium, particularly in east-central California, show as red areas.Northwest Pacific Coastal Mountains and Columbia Plateau: This area of volcanic basalts is low in uranium.

College Education Is The Question - 803 Words

To Go To College Or Not To Go To College That Is The Question One of the questions that plague many high school seniors is do I go to college or do I find a min wage job?

Is The Gender Pay Gap - 1880 Words

Seventy-seven cents to the dollar. A simple phrase used to describe the gender pay gap. Most people who use this phrase in casual conversation do not really know what this entails. It is much more than men earning more than women. The significance of this pay discrepancy becomes much more apparent when looking at the bigger picture. Over an entire lifetime of working, a woman making only 77 cents to the male dollar loses a total of $1.2 million dollars over the course of her working life (Murphy Graff, 2005). A risk of poverty for women living with a pay gap is high. According to the European Commission, the at-risk-of-poverty rate is around 22 percent for women, compared to the 16 percent of men. So why is the gender pay†¦show more content†¦The National Bureau of Economic Research points to labor market discrimination and overall trends in wage structure to explain why the wage gap exists. Discrimination in the labor market may lower women’s incentives to invest in their qualifications. The second factor of trends in wage structure refers to the terms the market sets for various skills or for employment in particular occupations or industries (Blau Kahn, 2001). Other factors contributing to the wage gap have since been considerably ameliorated, factors including gender gaps in education, skills, experience, as well as occupational segregation and career breaks (Kulow, 2013). According to Adam Smith’s The Wealth of Nations from the stimulus material, â€Å"The wages of labor in different employments vary according to the probability or improbability of success in them.† He then brings up an example of how mechanic jobs, such as carpentry and masonry, have almost certain success, meanwhile, success is very uncertain in the liberal professions. In a study done by the United States Department of Labor, the most common jobs for women consist of education administrators, teacher assistants, social workers, and secretaries- all the â€Å"liberal† professions. For men, their most common jobs include managers, carpenters, and laborers. The data, supported by Smith’s findings, prove that men do earn more than women, creating a gap in wages.

Essay about Religion Purification in Taxi Driver

Hes a profit and a pusher. Partly truth partly fiction. A walking contradiction. - Kris Kirstofferson In Martin Scorceses Taxi Driver, Travis Bickle repeatedly expresses two ideas that are central to the film. First, Travis has an undying wish to purify the world. He wants to rid his city of all the evil and scum that currently inhabits the citys cold and damp streets. Second, is the method by which Travis tries to obtain his goals. Travis Bickle tries to clean up his city by methods similar to those of religious figures. He even takes on a role as a savior figure. Travis Bickles quest to save the world via religious ideas fails, and instead results is a bloodbath. The first place where we are introduced to the†¦show more content†¦Much like Noah, he believes that he will be saved, while everyone else in the world perishes from the torrents of water. Later in the film, Travis feels compelled to take action against this sleaze. He wants to help purify the world by eliminating the sleaze by whatever methods he deems appropriate. Even if this means killing his fellow man, then so be it. Another instance where we see Travis revert to this theme of purifier is when he first meets Betsy. The childish scrawl in his diary tells the story. I first saw her at Palantine headquarters at 63rd and Broadway. She was wearing a white dress. She appeared like an angle. Out of this filthy mass. She is alone. They cannot touch her. In these few choice words, Travis Bickle again reemphasis the recurring religious references. In this specific instance, Traviss first words about his new love interest are, She was wearing a white dress. White is traditionally a color used to represent purity. In Traviss eyes, Betsy is the virginal ideal that he must strive to obtain. To him she is his perfect match. Possibly the most important aspect of this quotation is the religious references that it conjures up. Travis refers to Betsy as an angel; she is one of the few people who does not sink down into the muck that covers the city.

Blanche’s Death Speech Essay Sample free essay sample

Blanche’s decease address plays a critical function in the development of the drama â€Å"A Streetcar named Desire† . In the soliloquy the tenseness between Blanche and Stella comes to a zenith as Blanch explodes with fury as she expresses her jealousy-driven feelings to Stella. In making so Blanche reveals much more. including her unstable mental province. her emotional reaction to the doomed of Belle Reve. and most significantly her preoccupation with the subject of decease. One of the functions of this extract is to supply the background towards understanding Blanche. and the justifications for her mental province and actions. It is apparent that in the past she belonged to a higher category where extravagancy was common. But when her household in Belle Reve bit by bit died off. non merely did she hold to see the hurting of losing her loved 1s. but she was besides left with no money or fiscal assistance to maintain the estate and finally was forced to allow it travel. We will write a custom essay sample on Blanche’s Death Speech Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Blanche defends herself by figuratively stating that the inexorable harvester put up his collapsible shelter right on her doorsill and that is how â€Å"it slipped through my ( Blanche’s ) fingers† . She even goes on to impeach Stella of covering with the crisis by â€Å"ignoring† it and traveling on. hence go forthing Blanche to cover with an intolerable load. This is most obvious when she rhetorically asks Stella. â€Å"I allow the topographic point travel? † This quotation mark aids in taking the audience to comprehend that it was Stella that let the estate travel by non seeking to assist the state of affairs. To stress her point Blanche brings up the sarcasm of her being â€Å"at the bed when they ( her household ) cried out hold me† while reprobating Stella for being â€Å"In bed with your ( Stella ) – Polak. † During the address there are legion indicants that prove Blanche was profoundly hurt by her experience at Belle Reve. First. the apparently unneeded long account in itself demonstrates the importance of Belle Reve to Blanche. Second. the defeat and choler she expresses with Stella high spots the importance of their place to her. Throughout the piece Blanche repeats words and phrases many times underscoring her rage. For illustration. at the get downing she says. â€Å"I. I. I† . in the in-between she utters â€Å"I proverb. Proverb! Proverb! † and in the terminal cries â€Å"I allow the topographic point go! . I let the topographic point travel? † Third. it seems as if Blanche is impeaching Stella of faulting her for losing Belle Reve when in the book Stella merely asks about what happened. This becomes clear when Blanche reproaches Stella by stating her: â€Å"And you sit there stating me with your eyes that I let the topographic point go† and â€Å"Yes accuse me! Sit and stare at me believing I let the topographic point go! † This kind of assumptive attitude and thought influences the reader to presume that Blanche is unable to allow travel. In add-on when Blanche says â€Å"I took the blows in my face and body†¦Farther. Margret. Mother†¦had to be burnt like rubbish† she is besides straight conveying her torment. It is clear that Tennessee Williams carefully crafted this specific address to present the subject of decease. of which is recurrent in the class of the drama. He makes certain to depict the desolation of holding to cover with decease through Blanche. â€Å"Funerals are quiet but deaths- non always† . â€Å"Sometimes they even cry out to you. ‘Don’t allow me go’† . â€Å"Unless you were at that place at the bed when they cried out ‘Hold me’ you would neer surmise there was a battle for breath and breathing† . and â€Å"Why the Grim Reaper set up his collapsible shelter on our doorstep† are some quotation marks that specifically and deeply associate to the topic of Death. After reading these quotation marks and cognizing that Tennessee Williams suffered from hypochondria ( a misanthropic fright of decease and diseases ) . one could decode that Blanche’s mentality in this instance is about an emulation of the dramatist himself. Due to the construction of the address one could deduce that the organic structure linguistic communication of Blanche goes from heartache to anger to resentment and once and for all to gross out as she ends with that derogatory word – â€Å"Polak† . As you can see Williams smartly structures this one address to portray and supply tonss of valuable information about Blanche’s current province and past life ; this in bend foreshadows her inner and external struggles as the book progresses.

Paradise Essay Example For Students

Paradise Essay The Nobel Prize for Literature winner, Toni Morrison, is hailed as the lastclassic American writer , a major figure of national literature , and simply thebest writer in America. Morrison is at her complex and commanding best inthis mysterious tale, as she presents a unique perspective on American historyand leaves her dazzled readers shaking their heads over all that is perpetuallyinexplicable between men and women, rich and poor the tyrannical and freespirited. The statements above are merely personal opinions and have yet tobe proven true. After reading Toni Morrisons Paradise, I came to theconclusion that these remarks are over exaggerated. This is based on my opinionthat Paradise is not the writings of a Nobel Prize award winner and should notbe considered one of her best works. After all of the vivid descriptions of herwork, I can say that I was fairly disappointed. Paradise was the first and thelast of Toni Morrisons novels that I will read. After doing research intoothers an alysis of the novel, I realized that I was not alone in my judgmentof Paradise. I find myself troubled by this novel and how difficult it is tofollow. I dont mind reading slowly, in fact, I have no objection to taking mytime with anything; however, this is simply trying my patience. I wanted to keepgoing because I had invested so much of my time into reading the novel, but Ifind myself making excuses for not reading it. I wish Ms. Morrison had thoughtabout the impact of making the reading so challenging and had eased up on usjust a little bit. I am worn out from focusing on every word, but if I dont,then from one sentence to the next, I lose sight of a character, and then I amlost too! I just hope I can hang on long enough to get to the finish line,where, I know I will have to start all over again! I think this is theuniversal thought that goes through most minds after attempting to readParadise. I am not saying that the whole novel was awful because it was not. Ithought the theme o f the novel was incorporated well through out the novel. Theproblems were with the organization of the story line, and the development ofthe characters. The opening sentences of Paradise were attention grabbers. They shoot the white girl first. With the rest they can take there time. Noneed to hurry out here. They are seventeen miles between it and any other. Hiding places will be plentiful in the Convent, but there time and the day hasjust begun. The opening chapter is basically the climax of the plot. That is,a group of former law abiding male citizens attacks a group of unarmed women. This is what makes the story line confusing. That is, the beginning of the novelis the ending. Now the opening scene was good; but, instead of continuing fromthere, the story skips to the abandonment of Haven and the founding of Ruby. Theproblem was Ms. Morrison choose to tell the story in flashbacks. The story keptgoing back and forth in time and in different characters point of views. This ishow the story began to lose me. Paradise focuses on the all black town ruraltown of Ruby and the families who reside there. There were nine originalfamilies who founded the town. They are the Morgan, Blackhorse, Poole,Fleetwood, Beauchamp, Flood, Cato, and the two DuPres families. The descendantsof the nine original families create a version of paradise, hence the title ofthe book. The nine original families encouraged marrying among themselves topreserve the 8-rock blood. The 8-rocks were the pure blacks who did not have onedrop of white blood. These were the families with the dominance in Rub y. TheMorgans financed the founding of the town, owned the town bank and most ofthe land. Because of this, they felt they were the most influential and powerfulpeople in town. The families were tight knit and did not react well tooutsiders. The other characters are the women of the Convent, a former Catholicfoster outside of Ruby that has become a refuge for five women seeking an escapefrom the despair, abuse and emptiness of their lives. They are Consoleta(Connie), Mavis, Grace (Gigi), Seneca, and Pallas. I thought these characterswere underdeveloped. As soon as
