Polonium

The development of nuclear technology was one of the most significant achievements of the twentieth century. Nuclear medicine technique in hospitals use radioactive materials to treat patients. Medical radioisotopes have been used in nuclear medicine for many years for both diagnostic and therapeutic purposes. Atoms of an element that have the same mass number but different neutron numbers are known as isotopes. For diagnostic techniques, the radioactive isotope is injected or inhaled by the patient

historically dominate STEM fields, teaching women that this is not a suitable field of study. When asked about female scientists, most people identify Marie Curie. Marie Curie was a brilliant woman, discovering two elements of the periodic table, Radium and Polonium, as well as winning Nobel Prizes in Chemistry and Physics. However, most people know her simply as the woman who died from her radioactive experiments. Ada Lovelace worked with Charles Babbage to develop what would become the first computer by writing

Born as Maria Skłodowska on November 7,1867 in Warsaw, Poland, she was born to a family who viewed education as very important and essential. She had four siblings; four sisters Sofia, Helena, Bronislawa and a brother Joseph. Due to her father teaching Physics, Marie developed interest in reading and physics. She began to attend a “floating” school to learn since she couldn’t obtain higher education because she was a woman. She overcame many obstacles and discovered things that help cure diseases

word,”radioactivity” to describe the phenomena.Following her discovery of radioactivity, she continued her research with her husband. Working with the mineral pitchblende, the two discovered a new radioactive element in 1898. They named the element polonium, after Marie’s native country Poland. They also detected the presence of another radioactive material in the pitchblende and called it radium. In 1902, the two announced that they had produced a gram of pure radium, showing its existence as a unique

Abstract Radioactivity is the process that an atomic nucleus loses energy by emitting radiation to form a more stable atom, and time for radioactive material decay to half of the isotope is defined Half-life. Radon-220 observed in the experiment theoretically has a half-life with 54.5s. Two methods derived from the definition of Half-life and Radioactive Decay Law used to demonstrate half-life of Radon-220 under 400V and the closest result from the whole experiment is 55.90s with 2.57% error. The

It is very easy to fall in love with the hero. The nobleman who commits no wrong, saves the day, and usually looks good doing it. But the best characters aren’t thoroughly perfect and selfless like we would like them to be, because in the end, that’s not real-life. The best, most relatable characters are those in which we can associate, abhor, and admire all at the same time. Sophocles, William Shakespeare, and Arthur Miller were able to capture this character in the tragic hero. A character

interaction- similar to what was previously discovered Radio waves capable of doing, so she gave it the name «Radioactivity». Marie and her husband carried out more experimentations and managed to isolate two other radioactive elements; Radium and Polonium, and for that, they were awarded the Nobel Prize of physics along with Becquerel in 1903. Rutherford in 1899 demonstrated that uranium rays were composed of three different rays: alpha, beta, and gamma, with variable penetrating capacities. He

Alpha particles are unable to penetrate the outer layer of dead skin cells, but are capable, if an alpha emitting substance is ingested in food or air, of causing serious cell damage. Alexander Litvinenko is a famous example. He was poisoned by polonium-210, an alpha emitter, in his tea.

When he first find out about his father's death he immediately think someone has murdered him. When Claudius tells him that it was Hamlet ho had killed Polonium, he wants to find him and kill him on the spot. This is much more rash than what Hamlet's plan was and shows that Laertes is not afraid to take action. Another example of Laertes’s lack of bounds is when he says that he is willing to kill Hamlet

Henri Becquerel, who was a French physicist who discovered uranium casts off rays, weaker rays than the X-rays. Marie’s main discovery was to isolate the radioactive elements. Pierre and Marie discovered two new radioactive elements, radium and polonium. Because of all her exposure to radioactivity, she got leukemia. But as she left, she left another awesome women of science who also received Nobel Peace Prize in
