Becquerel did not discover that the amount of exposure on the paper was proportional to the amount of uranium that was present in the rocks
<h3>What is radioactivity?</h3>
The phenomenon of radioactivity was discovered by the French scientist Henri Becquerel in 1896 when he placed photographic paper in a drawer with some radioactive rocks.
