Essay on Physics: The Radium Element

In the early 1900’s, the discovery of a luminescent material, radium, arrived on the scene to the delight of a fascinated and eager public. At first, it seemed to be a miracle remedy, not just harmless but even beneficial. However, when a multitude of watch dial painters were exposed to this substance on an extremely consistent basis, the negative effects began bubbling to the surface. These “Radium Girls” were unknowingly consuming a potentially lethal substance and would be the first victims of radium poisoning and radioactivity. Not many people knew about the dangers of radioactive substances or radium poisoning and many others had made judgements that were clouded by the perfection of the glowing sensation. In spite of this, the horrific afflictions that the Radium Girls endured helped shift the public perspective of radium from “wonder drug” to “pitiless poison” and started the country on a path to regulating the handling of radioactive

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

From surgery to radium exposure to such extremes as radiation therapy, as doctors’ knowledge of the varying types of cancer, and the expansion of medical research regarding cancer has changed, so has the preferred method of treatment. Doctors and researchers dedicated to studying cancer have led to a greater understanding of cancer development; consequently the development of treatments and cures that are more effective, less harmful, have fewer side effects, and in some cases serve to prevent the spread of cancer.

Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They are not very penetrating so can be stopped by a piece of paper or skin. Beta particles have 1

Radium appears as a shiny, silvery metal of high radioactivity. Radium can be “used to treat prostate cancer that has spread to the bones,” and in the past, it was “used in luminous paints, for example in clock and watch dials” (Royal Society of Chemistry, 2017). Radium is present in the environment, and people that live in areas where coal or other fuels are burning and released into the air are more exposed to higher levels of radium. Radium can enter the body by breathing or swallowing and can remain in the body for months, only exiting in small amounts by urine and feces (“Public Health Statement for Radium,” 1990). High levels of radium exposure over a long period of time are extremely dangerous to the health of an individual. The harmful effects of radium could cause “anemia, cataracts, fractured teeth, cancer (especially bone cancer), and death” (“Public Health Statement for Radium,” 1990). The greater amount of radium exposure an individual receives, the greater their chance is to developing one of these diseases (“Public Health Statement for Radium,”

The city of Waukesha was “pleased to report” that their water tested negative for everything but Radium and Gross Alpha. Radium is element number 88 on the periodic table and from the name, you can guess that this element is highly radioactive and can be very harmful to the human body. For starters, if radium is ingested and absorbed into the cells and tissues, it can and will start to deteriorate the surrounding tissues. Specifically, radium may cause problems in the immune system including anemia. Radium can cause cataracts and fractured teeth (from breaking down tissue, including bone tissue). High levels of radium have also been known to cause an increased risk in bone, liver, and breast cancers. Gross Alpha is a type of radiation that is released when any naturally occurring radioactive element changes to produce a “decay product”, such as radium. These decay products are formed after billions of years. Alpha radiation is everywhere, in our soil, air, and in our water. This is because or earth’s bedrock consists of varying amounts of radioactive elements. The alpha radiation also varies in our water, due to the water in deep aquifers or wells touching the bedrock; the water may contain the same or less than the same amount of elemental decay. Alpha radiation in drinking / ground water can be in the form of dissolved minerals, or as a gas

Every element is special because none are ever the same. Even an atoms isotope is different. Krypton’s atomic number is 36. Its atomic mass is 83.798 units. The number of protons in an element, which is also the atomic number, is 36. It also

In the early 1900’s radium was “the latest miracle substance” (Hersher & Blum, 2014). Salesmen promised that it extended lifespans, increased sex drive, made women more beautiful, and had many other fantastic effects. The world was infatuated with radium and displayed this by putting it in slews of items including face cream, bread, chocolate, suppositories, toy sets for children, drinking water (as shown in figure 1), toothpaste, watch faces, and many more products. (List from scribal.com, 2007) It was used often in pharmaceuticals and described by advertisers as “nature’s way to health.” “Doctors used it to treat everything from colds to cancer.” (Hersher & Blum, 2014) However, the “magical” substance that was radium turned out to

The A simple definition of the word radioactiveis to have or develope a strong and dangerous form of energy. This could also be named radiation. A radioactive substance incvolves a very harmful form of energy that is developed betwen nuclear reactions. In the book "The Radioactive Boyscout" by ken Silversteint, there are several examples of radioactive substances being produced. The main character in the book is very as the title says "radioactive"

Q11. Marie curie took many leads in the world of science, one of them being; she won 2 Nobel Prizes in her lifetime and had a high place of honor in French history. Her study of radium was especially important, helping to change preconceived ideas as to how radioactivity worked. Even though she had opened maybe one of the largest Pandora’s Box and unleashed mortal danger to the world.

Krypton, atomic symbol of Kr, received its name from the Greek word kryptos, meaning hidden (Newton, 2010). This name is quite fitting seeing as the element is a colorless, odorless, and tasteless gas ("Krypton," 2007) at room temperature ("The Element

It is not until recently that people have become dependent on this element, and not necessarily for the good of it, and the world. There is an obsession with uranium because of its unique properties. Uranium is extremely powerful because of its radioactive properties and unstable nuclei, especially that of Uranium-235. It is able to break down and release high frequency radiation through alpha and beta decay. It is because of these characteristics that Uranium has such a craze on the population of the world (Cox, 1995; Scerri, 2007). The properties of uranium allow people to create powerful plants to produce electricity, and weapons strong enough to destroy the world.

Radioactivity is defined as “the spontaneous emission of particles”. (Nuclear Energy). Radioactivity is caused by an unbalanced nucleus in the cell. This happens because there is either an uneven number of protons and/or neutrons. When this happens, the element is considered to have multiple isotopes. An isotope is an atom with the same number of protons but a different number of neutrons. Thus, they have different atomic weights. This is important to know because there is a such thing as a radioactive isotope. These elements just have additional energy, and they release radiation in different forms. “There are over 800 radioactive isotopes, some of which are natural and some synthetic.” (Helmenstine). Radioactive elements can be both artificial and natural. However, in medicine, most of them are more than likely synthetic, since they are the most popular types.

     In July of 1898, Marie and Pierre Cure discovered Polonium. They named the element after Marie's birth country, Poland. Chemically, this new element was very similar to bismuth, but it contained radioactivity, so it must be new. In December of 1898, the Curie's discovered yet another element. They named this one radium, from the Latin word for ray. The two new elements had completely different chemical properties, but they both had very strong radioactivity.

I chose to do my project on Marie Curie, the woman who discovered radium and polonium. She was born Mary Sklodowska on November 7, 1867 in Warsaw, Poland and died July 4, 1934 in Passy, France at the age of 67. In 1895, Marie married a professor named Pierre Curie at the age of 26. She was the first woman to complete a doctorate in France in MMMM at the age xxx. And in MMMMM, Curie was also the first female professor at the Sorbonne. She was the first person to use the term “radioactivity”, which is the term still used till this day.
