Who first discovered radioactivity?
Becquerel
For his discovery of spontaneous radioactivity Becquerel was awarded half of the Nobel Prize for Physics in 1903, the other half being given to Pierre and Marie Curie for their study of the Becquerel radiation.
Who came up with the theory of radioactive decay?
The term radioactivity was actually coined by Marie Curie, who together with her husband Pierre, began investigating the phenomenon recently discovered by Becquerel. The Curies extracted uranium from ore and to their surprise, found that the leftover ore showed more activity than the pure uranium.
What is the theory of radioactivity?
Radioactivity is the property of unstable atomic nuclei to transform spontaneously. The process releases energy (usually by emitting ionizing radiation). Ionizing radiation is capable of removing electrons from atoms or molecules, leaving behind positively charged cations. …
How did Marie Curie discover radioactivity?
On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende.
What is the history of radioactivity?
In 1898 French physicists Pierre and Marie Curie discovered the strongly radioactive elements polonium and radium, which occur naturally in uranium minerals. Marie coined the term radioactivity for the spontaneous emission of ionizing, penetrating rays by certain atoms.

Who is famous for discoveries in radioactivity apex?
Marie Curie was definitely ahead of her time. Curie made scientific discoveries in the field of radioactivity that influenced the treatment of cancer and the advancement of nuclear power. She was also the first woman to receive the Nobel Prize in Physics for her work with uranium.
When was radioactivity invented?
1896
In 1896, Henri Becquerel announced the discovery of radioactivity to the Academy of Sciences in Paris after he discovered the radioactive properties of uranium.
Who invented Marie Curie’s xray?
scientist Wilhelm Roentgen
[2] Curie worked on the X-ray machine discovered by German scientist Wilhelm Roentgen in 1895. She used her newly discovered element, radium, to be the gamma ray source on x-ray machines.
Who is called the father of nuclear physics?
Sir Ernest Rutherford
Sir Ernest Rutherford, Lord of Nelson, died in October 1937. Forgive my too short account of his enormous history: he was the reference head of a community which is one of the most impressive in the history of science. Thus, the father of nuclear physics.
When did Marie Curie discover radioactivity?
1903 Prize: The 1896 discovery of radioactivity by Henri Becquerel inspired Marie and Pierre Curie to further investigate this phenomenon. They examined many substances and minerals for signs of radioactivity.
Who discovered two radioactive elements?
the Curies
And Marie was proven right: in 1898 the Curies discovered two new radioactive elements: radium (named after the Latin word for ray) and polonium (named after Marie’s home country, Poland).
Who was credited was the discovery of radioactivity?
A Frenchman named Henri Becquerel is said to be the person who discovered radioactivity. In the year 1896, Becquerel got some naturally fluorescent minerals to be used in an in-depth experiment. The purpose of the experiment was to study the properties of x-rays. The properties were already discovered a year ago by Wilhelm Roentgen, and Becquerel wanted to further examine it.
Who really discovered HIV?
In 1984, research groups led by Dr. Gallo, Dr. Luc Montagnier at the Pasteur Institute in Paris, and Dr. Jay Levy at the University of California, San Francisco, all identified a retrovirus as the cause of AIDS.
Who invented the theory of radioactivity?
The term radioactivity was actually coined by Marie Curie, who together with her husband Pierre, began investigating the phenomenon recently discovered by Becquerel . The Curies extracted uranium from ore and to their surprise, found that the leftover ore showed more activity than the pure uranium.
Who was famous for research on radioactivity?
Marie Curie. Marie Skłodowska Curie (/ˈkjʊəri/; French: [kyʁi]; Polish: [kʲiˈri]; born Maria Salomea Skłodowska; 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity.
