• French scientist defines radioactive
  1896

  French scientist, Henri Becquerel found that his photographic plates had become fogged, even though they had been protected from light.What this meant was that another source with properties of light, some rays, had penetrated the plates’ covering. He concluded that this effect came from compounds that he was working with containing uranium. Materials with such properties are called radioactive and include also thorium and potassium.
