All the isotopes of uranium are radioactive !
Radioactivity is discovered on uranium.
Uranium becomes lead

The radioactivity of uranium was discovered in 1896 by the French physicist Henri Becquerel.
Uranium is not artificial radioactivity so it is not clear what the question is about.
The fission of uranium-235 is an example of natural radioactivity, as uranium-235 is a naturally occurring radioactive isotope. Artificial radioactivity, on the other hand, refers to the radioactivity induced in a normally stable element through processes like nuclear reactions or particle bombardment.
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
The process by which materials give off energy from a uranium atom was named radioactivity by Marie Curie in the early 20th century. She discovered that certain elements, like uranium, emit radiation spontaneously.
uranium is mainly related to radioactivity so i think that it is widely used in these types of works.
radioactivity
Uranium's radioactive properties were discovered in 1896 by Antoine Becquerel.
Henri Becquerel discovered radioactivity in 1896 while conducting experiments with uranium salts. He accidentally found that photographic plates wrapped in black paper near a sample of uranium salts became fogged, indicating the emission of radiation from the uranium. This unexpected discovery led to further research and the development of the concept of radioactivity.
