Discovery of Radiation and Radioactivity Essay - 4326 Words.
Isotope - Isotope - The discovery of isotopes: Evidence for the existence of isotopes emerged from two independent lines of research, the first being the study of radioactivity. By 1910 it had become clear that certain processes associated with radioactivity, discovered some years before by French physicist Henri Becquerel, could transform one element into another.
Since these effects are produced both by salts and by pure uranium, radioactivity must be a property of the element and not of the salt. In 1899 E. Rutherford discovered and named alpha and beta radiation, and in 1900 P. Villard identified gamma radiation. Marie and Pierre Curie extended the work on radioactivity, demonstrating the radioactive properties of thorium and discovering the highly.
The discovery of the property of radioactivity gives us warning about its possible dangers. For one, there are certain places with high amount of radiation that are considered as off-limits to ordinary people. There are protective gears that were being required to be used in factories which somehow produce amounts of radioactive materials. Even natural sources of radiation such as that which.
In 1772, a Swedish chemist by the name of Carl Wilhelm Scheele made the same discovery that Priestley made. Unfortunately, he didn’t officially publish his findings until 1777, which was five years after his discovery. Priestley conducted several experiments to help understand the nature of oxygen better. He experimented with its role in respiration and in combustion. He also used oxygen in.
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.
Radioactivity Radioactive substances spontaneously emit rays that ar similar to X-rays, but these rays atomic number 18 generated from the actual substances. These continual emissions can last for months at a time without outside avail. An example of these natural substances are atomic number 92 and celestial longitude, they are undercoat in small quantities throughout the national of the.
The usage of nuclear chemistry through nuclear energy (ex. Nuclear power plants) in modern times has proven to have a minimal effect on the environment proving that Nuclear Chemistry is in fact beneficial to the world. Despite all of the great positive effects that nuclear chemistry has brought to the world through its existence, there are still quite a few negative effects it has on the world.
