The discovery of radioactivity took place over several years beginning with the discovery of x-rays in 1895 by Wilhelm Conrad Roentgen and continuing with such people as Henri Becquerel and the Curie family.
With the intention of further advancing the study of x-rays, Becquerel intended to place the concealed photographic paper in the sunlight and observe what transpired.
Unfortunately, he had to delay his experiment because the skies over Paris were overcast.
Rutherford was also able to observe that radioactive elements underwent a process of decay over time which varied from element to element.
In 1919, Rutherford used alpha particles to transmutate one element (Oxygen) into another element (Nitrogen).
Henri Becquerel learned of Roentgen's discovery of x-rays through the fluorescence that some materials produce.
Using a method similar to that of Roentgen, Becquerel surrounded several photographic plates with black paper and florescent salts.
Radioactive material is used in everything from nuclear reactors to isotope infused saline solutions.
These technologies allow us to utilize great amounts of energy and observe biological systems in ways which were unthinkable less than a century ago.
Instead, the salts left very distinct outlines in the photographic paper suggesting that the salts, regardless of lacking an energy source, continually fluoresced. Contributions: Pierre and Marie were award the Noble Prize in Physics in 1903 for their work on radioactivity.Tags: Adult Dating, affair dating, sex dating
