Uranium becomes lead
Become thorium-234 after ejecting an alpha particle and gamma ray. The thorium-234 continues to decay through 13 more decay events, ultimately becoming lead-126.

You can only say, 23 years later, I-131's radioactivity almost decreases to 1/8 of original radioactivity.
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
Radioactivity is caused by unstable atoms, that break apart.
Radioactivity is discovered on uranium.

All the isotopes of uranium are radioactive !
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.

Uranium's radioactive properties were discovered in 1896 by Antoine Becquerel.
