2. Henri Becquerel’s Life
Born December 15, 1852 in Paris, France
Alexander Edmond Becquerel, his father, was a Professor of Applied Physics
His grandfather was also a physicist
He received his doctorate degree in science in 1888

3. Contributions to the Atom
Becquerel discovered radioactivity and created a new understanding of the atom and atomic structure
He figured out that the nucleus of the atoms were disintegrating and throwing out a very fast particle that caused a clouding of the plates
Physical Science : About the Discovery of Radioactivity

4. Experiment Details
To recreate Becquerel’s experiment one would have to wrap a Lumiere photographic plate with a bromide mixture in two sheets of thick black paper
So the plate does not get cluttered when exposed to the sun for a day
Then the chemist would place the sheet of paper on a slab of the phosphorescent substance and expose it to the sun for a few hours
The photographic plate would have to be developed
The negative would show the experimentalist the silhouette of the phosphorescent substance

5. Conclusion
Once Becquerel proved gases ionized when the rays were given off by uranium and that they were different from X-rays in a way that they could be deflected by electric or magnetic fields, he was awarded half the Nobel Prize for Physics in (The other half was given to Pierre and Marie Curie for their study of the Becquerel radiation.)
Without Henri Becquerel’s discovery of radiation, the world today would not be what it is. Radiation therapy, medicine, academics, industry, all benefit from this discovery.
