Radioactivity was discovered in 1896 by Henri Becquerel, a French scientist, while testing phosphorescent materials with photographic plates. He discovered that, when the plates were covered with black paper, that phosphorescent materials did not affect the plates until he used uranium salts.
It was Henry Becquerel, that first discovered the radioactive decay of the element uranium in 1896. Becquerel was a French physicist.
Radioactivity was discovered in1896 by Henri Becquerel when he was using uranium salts in an experiment to determine the cause of phosphorescence.

Radioactivity was discovered on March 1, 1896, by a French physicist named Henri Becquerel, this discovery is now known as one of the most famous accidental discoveries in the history of physics. Becquerel was then awarded half of the noble prize for physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.
Henri Becquerel shared a Nobel award in 1903 with Marie and Pierre Curie for the discovery of spontaneous nuclear radiation through experiments in 1896 involving the phosphorescence of Uranium Salts; specifically, potassium uranyl sulfate.

Uranium is not artificial radioactivity so it is not clear what the question is about.
Radioactivity was first discovered in 1896 by the French scientist Henri Becquerel.
Becquerel discovered x-rays and radioactivity in 1896.
Marie Curie discovered RADIUM. Sir Henry Becquerel found radioactivity in 1896.
The discovery of radioactivity is accredited to Henri Becquerel, a French scientist who discovered it in 1896.
Becquerel discovered the natural radioactivity of uranium in 1896.
henri bacquerel discovered radioactivity in 1896.Artificial radioactivity was first discovered by Joliot Curie and her husband in 1934 while studying the effect of alpha particle bombardment on like elements like Aluminium
Henri Becquerel discovered in 1896 the natural radioactivity.

Radioactivity was discovered during 1896 by Henri Becquerel, who was a French scientist when he was working on phosphorescent materials. Other research was done by Becquerel, Ernest Rutherford, Paul Villard, Pierre Curie, Marie Curie, and others afterwards.
