One possesses the key to unlock the undiscovered mysteries of life. Leading to future advancements, the discoveries made will trigger society to benefit appreciably. For instance, Marie Curie, an influential scientist, greatly benefitted society in a variety of ways. Her unforgettable and inspiring accomplishments, such as her work on radioactivity and discovery of polonium and radium, triggered a new field of physics. Furthermore, she ignited attention towards the interior of the atom and led to her contribution during WWI.
Discovering the elements, polonium and radium, Marie Curie considerably affected society in various ways. Polonium became utilized in small mobile radiation appliances. For example, it was applied in the radiation sources that initiated heart pacemakers, which assisted the heart to beat more regularly (Felder 9). In addition, the radiation sources applied to manage static electricity contain polonium, which reduced the enormous number of fires and explosions in numerous industries. As a result, safe industries were established, preventing a multitude of deaths (Felder 9). Furthermore, radium impacted society positively as well. Since radium is capable of emitting light, it was utilized in nightlights. Moreover, health spas sprouted, pleasing both men and women. Radium mud and water arose from radium and became used in the spas (Crezo). They left the skin feeling soft and looking healthy. After a while, radium cream developed and flourished society. Furthermore, radium was utilized in chocolate, toothpaste, and makeup before the risks were revealed (Crezo). In addition, radium also emits gamma rays, which killed cancerous cells. Thus, it became used to treat medical conditions such as cancer (“Radium Uses”)

...ute tries to treat and fight cancer, which hopefully will save abundant lives. Safety rules were set up for the workers because radium was a dangerous element to deal with. They had to wear lead shields on their hands to prevent from any harm and damage (Huso). In addition, the Curie Institute manages with 13,000 patients every year. Furthermore, the institute provided a job for 3,200 collaborators (“Marie Curie Charity Gala 2013”).
Marie Curie affected society in the past as well as today. Thus, she is known as one of the most influential women of all time. Her unforgettable achievements have left a permanent mark in history. Her hard work, which led to her fantastic efforts will always be treasured in one’s heart and mind. All in all, Marie Curie’s outstanding accomplishments altered society in a positive way, which should be rewarded with a standing ovation.
In chapter 8 titled "Radium (Ra)" of The Poisoner's Handbook by Deborah Blum, the most interesting story developed within this chapter was the death of dial workers at Orange, New Jersey after been exposed to radium every day. It was interesting due to the fact that radium was used everywhere in the community and was never thought it could harm anyone. Radium was a super element that was used everywhere, but its continuous use unmasked its fatal habits. As it was stated in the text, "Radiant health, the ads proclaimed-beautiful skin, endless vigor, and eternal health—ingesting radium seemed the next best thing to drinking sunlight." (Blum 179). People were accepting radium as a natural gold element but they haven't realized constant contact
(Brown 166). This radioactive element that workers produce is not just affecting the environment, but is also affecting the workers and their families. Brown has given an immense amount of evidence to explain to the readers how it affected so many of the workers’ health; she gives a vivid picture of how the radioactivity and particles of plutonium linger in the air. The effects to the workers and their family range from cancerous cells to organ deterioration, when a pregnant woman is exposed to it, the health of her baby is also at risk. The fourth and last part of the book is “Dismantling the Plutonium Curtain,” this curtain is the curtain of secrecy.
...to establish the tolerance level for radium. The center for Human Radiobiology was established in 1968 with the primary purpose of examining living dial painters.
For a long time, women’s potential in Science was little to none. However, over the years, it has now changed because of the outstanding breakthroughs and encouraging accomplishments women have done through the years. It is because of them, women’s potential in Science and other realms of studies has now evolved with more understandings and discoveries. It is for the reason of Maria Mitchell, one of the first female astronomers to be recognized in Science, that women’s potential were essentially respected. Her discoveries during her time as a student, a teacher, and an astronomer paved the way for many others, not just in Science, but also for woman’s rights and potential to be seen.
Throughout the novel, Skloot recounts some of the great advancements in biomedical research. Media outlets often prematurely declared these great advancements as the solution to all disease. Similar to this case is the discovery of radium. In the 1800’s, radium was deemed to be “a substitute for gas, electricity, and a positive cure for every disease” (Skloot 46). Radium kills cancer cells, but it also kills healthy cells, as well. Notably, to treat Henrietta’s aggressive cervical cancer, doctors used radium, “[Henrietta] began burning inside, and...
...vercome, there is more of a chance to capture such great discoveries. People need to realize that if they never take the time to stop and look around, appreciate the small things in life, they might miss out on important details and or moments that the world has to offer. Scientist didn’t obtain their greatest discoveries by looking at the world with a closed mind. During the months of September through Novemeber, the leaves start to fall off the trees. It is obvious its fall, but what else is occurring? Gravity. Albert Einstein discovered gravity by watching and ordinary object fall. At that moment he became a scientific unscrupulous observer.
Marie Curie (1898-1934): Marie Curie was a Polish physicist and chemist who conducted pioneering research on radioactivity. In 1903, she shared the Nobel Prize in Physics with her husband, and in 1911 won the Nobel Prize in Chemistry. She was the first woman to win a Nobel Prize, the first person and only woman to win the Nobel Prize twice, and the only person to win a Nobel Prize in two different sciences. Through her experiments she developed the theory of radioactivity and techniques for isolating radioactive isotopes, as well as discovering two new elements: radium and polonium.
When most people think of the Scientific Revolution, they think of scientists such as Galileo, Newton, Brahe, and Boyle. However, many people do not even know about the many women who played a vital role in the scientific advancements of this period. Even when these women were alive, most of society either ignored them or publicly disapproved their unladylike behavior. Because of this, these women were often forgotten from history, and very little is known about the majority of them. Although their names rarely appear in history books, the female scientists of the Scientific Revolution still impacted the world of science in several ways. In fact, all of the scientists listed above had a woman playing an influential role assisting them in their research. However, assisting men in their studies was not the only role open to women; several women performed experimentation and research on their own, or advancing science in some other way, even though the society of the time looked down upon and even resisted their studies.
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
Marie Curie was one of the shy girls, but yet one of the most famous scientists in the world. She could care less about the money, the fame, and the attention, science and research are the only things she thought about. She never did understand why people were so interested in her, her discoveries, why her?
Uranium, a radioactive element, was first mined in the western United States in 1871 by Dr. Richard Pierce, who shipped 200 pounds of pitchblende to London from the Central City Mining District. This element is sorta boring but I found something interesting, they used it to make an an atomic bomb in the Cold War. In 1898 Pierre and Marie Curie and G. Bemont isolated the "miracle element" radium from pitchblende. That same year, uranium, vanadium and radium were found to exist in carnotite, a mineral containing colorful red and yellow ores that had been used as body paint by early Navajo and Ute Indians on the Colorado Plateau. The discovery triggered a small prospecting boom in southeastern Utah, and radium mines in Grand and San Juan counties became a major source of ore for the Curies. It was not the Curies but a British team working in Canada which was the first to understand that the presence of polonium and radium in pitchblende was not due to simple geological and mineral reasons, but that these elements were directly linked to uranium by a process of natural radioactive transmutation. The theory of radioactive transformation of elements was brilliantly enlarge in1901 by the New Zealand physicist Ernest Rutherford and the English chemist Frederick Soddy at McGill University in Montreal. At dusk on the evening of November 8, 1895, Wilhelm Rontgen, professor of physics at the University of Wurzburg in Germany, noticed a cathode tube that a sheet of paper come distance away. He put his hand between the tube and the paper, he saw the image of the bones in his hand on the paper.
...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
Radiation is a frightening concept. It has lead to many an untimely death in the past 70 years, ranging from victims of atomic bombs in Japan to physiologists experimenting without taking proper safety precautions. The most dangerous form of radiation can be devastating to the body, weakening or eliminating the immune system and tearing the very DNA in one’s cells apart. This form is referred to as ionizing radiation, and even the least harmful potencies - such as x-rays and UV light - can increase the risk of cancer and other health problems. It has enough energy to knock electrons out of atoms in a process called ionization.
Marie Curie. A Polish and naturalized-French physicist and chemist, who conducted pioneering, research on radioactivity. She was the first woman to win a Nobel Prize and the first person and only woman to win twice. Among her discoveries including two new elements, isolating radioactive isotopes, she developed mobile radiography units to provide X-ray services to field
The impact of nuclear power on the modern world has improved Various sectors of the economy and society .i.e. Food and Agriculture, Insect control, Food Preservation, Water Resources, Military, Medicine, Research and Industry. “In 1911 George de Hevesy conducted the first application of a radioisotope. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed.
