Origin of radioactivity
WitrynaA beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.There are two forms of beta decay, β − decay and β + decay, which produce electrons and positrons respectively.. Beta particles with an energy of … Witryna5 sty 2012 · Hence a sea-water origin for the abnormally high radioactivity at Niue is unlikely. A separation from uranium of the daughter products, ionium and radium-226 (the main elements at Niue), takes place in hydrothermal solutions as well as in sea water. The latter could have come from the volcanic substructure at Niue, which could have …

Perhaps the first attempt to come up with an atomic explanation of radioactivity was made by George Stokes in a lecture of July 2, 1897, at a time when it still made sense to conceive radioactivity as intermediate between ordinary light and X-rays. In redhill works nottinghamWhile conducting experiments with electricity and vacuum tubes in 1895, Wilhelm Röntgen discovered that his photographic plates were darkened, even when wrapped with black paper.
