Uses of Radiation in the Medical Industry Although scientists have only known about radiation since the 1890s, they have developed a wide variety of uses for this natural force.Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity.In addition, radiation has uses in such areas as agriculture, space exploration, law enforcement.
Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of radiation. By covering his Uranium with thin foils of aluminum, gradually increasing the number of foils.
Marie CurieLIFE OF MARIE CURIEMarie Curie(1867-1934) was a French physicist with many accomplishmentsin both physics and chemistry. Marie and her husband Pierre, who was also aFrench physicist, are both famous for their work in radioactivity.
The significance of atomic nuclear decay is that the decay is a waste material that is classified as hazardous to organic based life. The instability of the nuclear waste is also an issue as the radioactivity of the waste will remain highly radioactive and unstable for hundreds of thousands of years.
Bookmark; Glossary Terms; Traditional chemical reactions occur as a result of the interaction between valence electrons around an atom's nucleus (see our Chemical Reactions module for more information). In 1896, Henri Becquerel expanded the field of chemistry to include nuclear changes when he discovered that uranium emitted radiation.Soon after Becquerel's discovery, Marie Sklodowska Curie.
Marie Curie Marie Curie was born Maria Sklowdaska on November 7th, 1867. She was the fifth and youngest child in her family. Times were tough living in the Russian parition of Poland, and her family suffered many financial hardships.
Discovery of Neutron From the previous discussion, we can see that the gold foil experiment gave a clear picture of the structure of an atom which consists of protons (nucleus) and same number of electrons outside of the nucleus.

Essay: Internal Structure of the Earth.. It is a fairly recent discovery to prove that the mantle of the earth is not the only part of the interior.. The continuing contraction of these materials caused them to heat, as did some of the radioactivity of some of the heavier elements.

In our times, the history of science created three great divisions for the research fields: natural, social and technical. Scientific fields differ both in history and in their subjects and methods. At the same time, there is no defined edge between them, and there are scientific disciplines with an interim position: For instance, biotechnology, radiogeology, etc.
More Compose Quotes Some truths there are so near and obvious to the mind that a man need only open his eyes to see them. Such I take this important one to be, viz. that all the choir of heaven and furniture of the earth, in a word all those bodies which compose the mighty frame of the world, have not any subsistence without a mind that their being is to be perceived or known.
Their first accomplishment was to show that radioactivity was a property of atoms themselves. For scientists it was the most important of Curies discoveries, because it helped other scientists to understand the atomic structure of matter. The second, more famous discovery, was the discovery of polonium and radium.Marie Cuie Essay Sample.. working mainly in France,(2) who is famous for her pioneering research on radioactivity. She was the first woman to win a Nobel Prize,. a theory of radioactivity (a term that the Curies coined), techniques for isolating radioactive isotopes, and the discovery of two elements, poloniumand radium.Atomic theory is a scientific description of the nature of atoms and matter that combines elements of physics, chemistry, and mathematics. According to modern theory, matter is made of tiny particles called atoms, which are in turn made up of subatomic particles.Atoms of a given element are identical in many respects and different from atoms of other elements.
