Pierre and Marie Curie were the first people to discover radioactivity.
Marie Curie discovered RADIUM. Sir Henry Becquerel found radioactivity in 1896.
February in the year of 1896
artificial radioactivity.
Yes mam she was
Her and he husband Fredrick Joliot-Curie discovered artificial radioactivity ... !
Uranium's radioactive properties were discovered in 1896 by Antoine Becquerel.
Henri Becquerel discovered in 1896 the natural radioactivity.
Henri Becquerel discovered in 1896 the natural radioactivity of uranium.
In fact, Bequerel had first discovered radioactivity from uranium in 1896, by fogging of photographic plates. The Curies however used an electrometer which her husband had invented, and which reacted to ionisation in the air, which was produced by radioactivity. This enabled her to deduce that radioactivity came from the atoms of the substance, not some sort of chemical reaction. She went on to discover radium in pitchblende, which was the first knowledge of it, and a number of other achievements. See the link below for more information on her discoveries.
Marie Curie (although she did not 'discover radioactivity'; that was Becquerel)
The first thing Marie Curie discovered was Becquerel's rays but called it radioactivity after her home land.
