Recommended: Discovery of radium and medicine
Radium is the 88th element on the periodic table, that gave off high levels of radioactivity, and for the first twenty years it was a magical healing substance that glowed in the dark. Introducing, this element to the human populace began both innovations to health science and tragic deaths of many who believed it was harmless.
Radium was discovered by Marie and Pierre Curie when Marie was looking for a subject to do her doctorate in physics. During that time, a scientist named, Henri Becquerel was testing uranium salts in sunlight to determine the aspects of its radiation and glow. Becquerel accidentally found a new type of substance while he was doing these tests that illuminated without needing the uranium salts. Marie Curie found
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
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...
Strontium was discovered by Adair Crawford, an Irish chemist, in 1790 while studying the mineral witherite (BaCO3). When he mixed witherite with hydrochloric acid (HCl), he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite (SrCO3). Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl2) and mercuric oxide (HgO). Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water. Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is very
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.
he found the number of alpha particles emitted per second by a gram of radium.
This uneasiness is a result of events over the past one hundred years showing the dangers of radiation. Although most accidents today leading to death from radiation poisoning occur from human error or faults in equipment, the incident involving the now named "radium girls" transpired from lack of public awareness and safety laws. (introduce topics of the paper) The Radium Luminous Material Corporation was founded in 1914 (renamed in 1921 to the United States Radium Corporation) by Dr. Sabin Arnold von Sochocky and Dr. George S. Willis becoming the first U.S. company to produce radioluminescent paint. The paint used by this particular company was the trademarked "Undark", invented by William J. Hammered through mixing radium, zinc sulfide and glue with the help of Marie and Pierre Currie and Henri Becquerel.
MARIE CURIE AND THE STUDY OF RADIOACTIVITY Marie Curie was born, Maria Sklodowska, on November 7, 1867. She grew up in Warsaw, Poland. She would become famous for her research on radioactivity. Marie Curie was the first woman to ever win a Nobel prize, and the first ever to win two Nobel prizes. She is most famous for the discovery of Radium and Polonium.
A radioisotope is an isotope that emits radiation as it has nuclear instability(Prostate Cancer; Fusion imaging helps target greater doses of radiation).Those who are not too familiar with radioisotopes may think their use is for harmful radiation, nuclear weapons, and the possibility of turning into a giant, raging, green monster. However, there are much more positive uses for radioisotopes. There have been many medical advances thanks to the benefit and practice of radioisotopes in nuclear medicine. These advances have been able to diagnose and treat a variety of diseases.
In their search for the elusive philosopher’s stone, alchemists conducted experiments that lead to many enlightening scientific discoveries. Late alchemists are sometimes better known as scientists; the chemist Robert Boyle and the physicist Sir Isaac Newton were among them. In 1898, there was a discovery that seemed to finally prove that transmutation was impossible. Rutherford’s gold foil experiment revealed the existence of the nucleus, and the number of protons in the nucleus determines the element (Rutherford). Since lead and gold have different numbers of protons in their nuclei, and there was no known way to change this, as a chemical reaction does not change the nuclei of atoms.
Wilhelm Roentgen discovered radiation which is also known as x-ray in 1895. Radiation is energy turned into waves or particles in
Pierre's sudden death in April 1906 was a difficult blow to Maria, but a turning point in her career: she was devoted to completing the scientific work they had started. In 1911 her determination paid off, she won a second Nobel Prize (this time in chemistry) for her discovery and isolation of pure radium and radium components.
X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory. He sent electricity through the cathodre-ray tube and noticed something strange his laboratory. He saw a flash of light from a sheet of paper coated with barium platinocyanide that he had unknowingly left on a table at the other end of the lab. Roentgen knew that cathodre-rays could not penetrate the black box and that they only travel short distances. So he deduced that another form of radiation emitted from the cathode tube was causinq the luminescence. Roentgen called this new unknown radiation X-rays. X being the mathematical symbol for a unknown.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
Even the neutron, discovered by James Chadwick, owes its name to Rutherford. The exponential equation used to calculate the decay of radioactive substances was first employed for that purpose by Rutherford and he was the first to elucidate the related concepts of the half-life and decay constant. With Frederick Soddy at McGill University, Rutherford showed that elements such as uranium and thorium became different elements (i.e., transmuted) through the process of radioactive decay. At the time, such an incredible idea was not to be mentioned in polite company: it belonged to the realm of alchemy, not science.
What is radioactivity? Radioactive isotopes are heavy nuclei of certain elements having extra neutrons. The extra neutrons in their nuclei cause them to be unstable so the nuclei break up spontaneously, emitting alpha, beta and gamma radiations. For example,
