Glenn T. Seaborg's Life: Glenn T. Seaborg

Superior Essays
Glenn T. Seaborg was born in Ishpeming, Sweden in 1912, into a family known publically as being intelligent. However, in 1922, the family moved to California in order to expand their opportunities. In high school, he had no interest in science. However, a science class was required for graduation. A teacher named Dwight Logan Reid is given credit for his interest in the field. Due to his family’s finances, the nearby University of California at Los Angeles (UCLA) was his only option; due to its free tuition. Financial hardships were common throughout Seaborg’s childhood and early adulthood due to the Great Depression in 1929 to 1939. However, these financial barriers exhibited throughout the book represent Seaborg’s ability to succeed in the …show more content…
Hamilton needed a radioisotope that had a half-life long enough to be made useful in the human body, one that was about a week. Seaborg and his long-time friend and partner Jack Livingwood used targets of tellurium and bombarded it with deuterons and some with neutrons to reveal iodine 131, which had a half-life of eight days. (talk about iodine 131’s importance). In Seaborg’s life, the meaning of this element held major importance due to its aid in his mother’s cure of hyperthyroidism. Seaborg and Jack also discovered cobalt 60, which is also a critical medical isotope. Cobalt 60 emits gamma radiation which in turn focuses directly on cancer cells to destroy it. “Hundreds of thousands of Americans have had their cancers treated by cobalt-60 irradiation, and it is also used to sterilize medical products and equipment” (36). Shortly later, Seaborg and David Graham, his fellow graduate classmate, borrowed their professors radium-beryllium neutron source to disprove a theory reported by a Japanese scientist named Seishi Kikuchi. They concluded that the neutrons involved were colliding with a nucleus rather than electrons. In fact, the Japanese scientist acknowledged their results and sent a letter apologizing for their mistake. Professor Lewis was an intelligent and well respected professor, who students and other staff members tended to be intimidated by. …show more content…
Together, they broadened the definition of acids and bases. Bases were now elements that included any molecule that could donate an electron to be shared. Consequently, A Lewis base is any species that donates a pair of electrons to a Lewis acid to form a Lewis adduct. Throughout their work with acids and bases, Lewis taught Seaborg the research method of breaking a big project into small parts; which he later used in the Manhattan Project. Before his research assistantship expired, he began instructing in the chemistry department in 1939. In working with Emilio Segré in Berkley’s Radiation Lab, he and Seaborg collaborates on research into the isotopes of element 43. They discovered in return, an isotope that had an interesting radioactive decay pattern, emitting intense, short-lived gamma rays known as technetium 99. Technetium is now a major factor in nuclear medicine in its use of diagnostic imaging involving thyroid, bone, liver, spleen, lung, brain, kidney, and cardiovascular disordered. However, these medical uses did not appear until much later. Ernest Lawrence, the inventor of the cyclotron, played a

    Marie also created the building blocks for radiotherapy; radiotherapy is a treatment used to remove cancerous tumors from the body. Marie Curie not only impacted the world of medicine ,but also impacted chemistry by finding two new elements: radium and polonium. Curie not only discovered the radioactive elements ,but also proved her theory on the structure of an atom. According to the biography, Marie Curie chemistry, physics and radioactivity by Michelle Feder it states, “She suggested that the powerful rays, or energy, the polonium and radium gave off were actually particles from tiny atoms that were disintegrating inside the elements… But the Curies’ research showed that the rays weren’t just energy released from a material’s surface, but from deep within the atoms. This discovery was an important step along the path to understanding the structure of the atom.” Marie Curie discoveries in radioactivity have made major impacts in…

    The Atomic Bomb Lighting the Way for Radiation Protection Even though radiation has been around since the beginning of time there was little known about it. When x-rays were discovered in 1895, radiation research followed suit right after. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States to be the first with the atomic bomb began with this knowledge. With the help of several scientists the United States succeeded of building the atomic bomb first.…

    (Choppin, Liljenzin and Ridberg) Chemistry is used in the field of medicine to diagnose and treat diseases. The process is usually conducted by radiographers can also be referred to as endoradiology. The process involves radioactive drugs inserted into the patient through injection. Before the uses of nuclear chemistry in medicine are discussed, it is vital to study the chemistry of nuclear and radioactivity. A nuclide consists of protons and neutrons in any configuration.…

    That same year, in 1896, Pierre and Marie Curie, the first woman to receive the Nobel Prize, coined the term “radioactivity” and were able to isolate the elements Polonium and Radium, later used for medical treatment, from pitchblende. A couple years later, in 1898, Samuel Prescott demonstrated that radiation destroyed the bacteria in food, illustrating the first experiment acknowledging the destructive abilities of…

    Through the use of radioactive materials discovered decades earlier by Marie Curie, radioactive material could be converted into electrical energy. The newly discovered nuclear energy was highly efficient and produced minimal amounts of waste. Thusly, the US created the Atomic Energy Commision in 1946 in order to develop and improve atomic technology. The AEC would continue to spend over 10 years and upwards of $500,000,000 in order to test and design the first nuclear power plant. And on February 7th, 1957, American engineer Hyman Rickover successfully activated his Pressurized Water Reactor outside of Pittsburgh, creating America’s first nuclear power plant.…

    Probably, the first thing that came to mind when you saw this, was… What exactly is the Manhattan project? Well the Manhattan project dates all the way back in 1938, when many people feared that Hitler would build an atomic bomb after word spread that German scientist had split the uranium atom (fission). However, one of Hitler’s mistakes was his persecution of Jewish scientists. This persecution resulted in numerous scientists seeking asylum in the United States. One such scientist was Albert Einstein.…

    Under Rutherford, he devised a means of measuring gamma radiation, and proceeded to measure the absorption of gamma rays by various gases and liquids. He worked heavily with atomic numbers and with forces inside the nucleus. Chadwick continued his research well into the second world war, and became deeply involved in the atomic bomb. He was reached out to by the government asking for his opinion on the possibility of an atomic weapon and responded skeptically. However, this made him curious and together with Rudolf Peierls discovered the power of gaseous uranium-235.…

    For example, “radioactive iodine (specifically iodine 131) is frequently used to treat thyroid cancer, a disease that strikes about 11,000 Americans every day.”("Uses of Radiation."). Radiation is also used for the sterilization of medical instruments. By subjecting them to beams of concentrated radiation, micrograms that cause contamination and disease can be killed. “Because this is done with high energy radiation sources using electromagnetic energy, there I no fear of residual radiation, [therefore] the instruments [can] be held without fear of radiation poisoning.”("Uses of Radioactivity”). While there is a debate that radiation has not changed medicine for the better due to a risk of radiation poisoning, this is incorrect in the fact that radiation is done with high electromagnetic energy causing the risk of radiation poisoning to go down.…

    The transition into the atomic age began in the early 1900s, when scientists began researching the atom. In 1938 they discovered something called fission, the process of splitting an atom. Due to the second world war breaking out the research of atoms eventually turned to the research of weapons. A few of the leading countries in the race for an atomic weapon were Germany, the United States, and the Soviet Union. After several years of research the U.S. developed and tested the first atomic bomb named either the Gadget or project Trinity.…
