Henri Becquerel: The Discovery of Radioactivity

Henri Becquerel is probably not the name that rings in your head quite as much as that of Albert Einstein or Marie Curie, but he contributed a great deal to how we comprehend the world and science today. Antoine Henri Becquerel was a French physicist who had made this far-out discovery that changed the concept of atoms and energy. This blog will discuss Henri Becquerel discovery and his life, and how it shaped the science of radioactivity. We take into consideration the processes of his experiments and what they mean to us today.

Early Life and Education of Antoine Henri Becquerel

His full name, Antoine Henri Becquerel, was born on 15 December 1852 in Paris, France. He entered a generation of scientists born as his descendants—a hereditary family that had to stimulate something great within his interests. His father, Alexandre-Edmond Becquerel, was a professor of physics and dealt with solar radiation, while his grandfather, Antoine César Becquerel, was equally a renowned scientist. Given the conditions that Henri received, such an unshakable scientific background made it naturally predictable that he would inherit the family's interests.

Henri Becquerel had attended science and engineering at École Polytechnique in France, one of the most esteemed engineering schools in the country. He then became an engineer, but studied physics. Ultimately, his interest in science and his curiosity about the world around him led him to make one of the most important physics discoveries.

In 1889 he was elected to the Academie des Sciences de France and succeeded to the life secretaryship of that body vacant by the death of Berthelot. He was a member, amongst others, of the Royal Academy of Berlin and the Accademia dei Lincei. He was made an Officer of the Legion of Honour in 1900.

He was married to Mademoiselle Janin, the daughter of a civil engineer. His son Jean, born in 1878, became a physicist too, belonging to the fourth generation of scientists in the Becquerel family.

Henri Becquerel Discovery of radioactivity 

The Henri Becquerel discovery of radioactivity  is considered one of the most outstanding feats in the annals of science. It was all started by a newfound fascination with a phenomenon called X-ray. Discovered by Wilhelm Conrad Roentgen in 1895, X-rays could penetrate solid objects giving images of the inside of human bodies. This was a remarkable discovery, and scientists from many countries were eagerly trying to understand what it was all about.

Becquerel wondered if there existed other forms of invisible radiation, similar to X-rays, but which could occur naturally. He opted to investigate this using a material known as uranium, which, by definition was a naturally occurring mineral. In early 1896, Becquerel carried out an experiment that would change science forever.

The Famous Henri Becquerel Radioactivity Experiment

Henri Becquerel's experiment on radioactivity started from a very simple question: Did uranium also emit radiations along the lines of X-rays? To test the idea, he wrapped a photographic plate in black paper so that it could not be reached by any light. He then left a piece of uranium on top of the covered photographic plate and left it in a dark drawer.

Initially, Becquerel thought the uranium needed sunlight to become excited and emit its radiation. When he developed this photographic plate some time later, he was in for a big surprise-the plate was fogged, even though it had been kept in darkness. The fact that it was fogged showed the uranium emitted some sort of invisible radiation which could pass through the black paper and have an effect on the plate.

That experiment meant that uranium gives off some kind of radiation of its own without sunlight's or, indeed anything else acting on the uranium. That radiation that we cannot see is nowadays termed as radioactivity. It was wholly and entirely a unique phenomenon. Henri Becquerel had observed this radiation – one that gained its name, radioactivity, much later by the famous scientist Marie Curie, who would take his work much further.

The Impact of Henri Becquerel Discovery

The discovery of radioactivity was a revolutionary finding within science, since it had evidenced the breaking down of atoms, which were previously thought to constitute the smallest and most stable units of matter, releasing energy. This opened new areas of research in physics and chemistry that led, years later, to the development of nuclear energy and techniques of medical imaging, such as the PET scan.

Lastly, Henri Becquerel's personal discovery of radioactivity opened doors for more scientific discoveries in the aspect for others—Marie and Pierre Curie. The Curies are accredited with the discovery of two new radioactive elements: polonium and radium. Their work assisted in the understanding of nature pertaining to radioactive decay.

For such a monumental discovery, Henri Becquerel later shared the Nobel Prize in Physics with Marie and Pierre Curie in the year 1903. This prize stood for his recognition as one of the most important pioneers in the creation of modern physics.

Henri Becquerel's Contributions to Science

Yet, although the discovery of radioactivity brought him the greatest fame, Henri Becquerel did not stop there. He worked all his life on different aspects of physics, such as the interaction of light with various materials.

Becquerel's research on phosphorescence—wherein some materials glow in the dark after exposure to light—was particularly significant. His work in this area has helped our understanding of how light reacts to matter, with applications in fields ranging from material science to biology.

Apart from scientific research, Henri Becquerel was a great teacher and mentor. He was a professor at the Museum of Natural History in Paris, whereby he influenced young minds to pursue their careers in physics.
