What exactly is radioactivity?
As its name implies, radioactivity is the act of emitting radiation spontaneously.
This is done by an atomic nucleus that, for some reason, is unstable; it “wants” to give up some energy in order to shift to a more stable configuration..
How did Marie Curie’s work change the world?
Indefatigable despite a career of physically demanding and ultimately fatal work, she discovered polonium and radium, championed the use of radiation in medicine and fundamentally changed our understanding of radioactivity. Curie was born Marya Skłodowska in 1867 in Warsaw.
Who discovered radioactive?
Henri BecquerelIn one of the most well-known accidental discoveries in the history of physics, on an overcast day in March 1896, French physicist Henri Becquerel opened a drawer and discovered spontaneous radioactivity.
Who is the father of radioactivity?
BecquerelFor 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.
How did Marie Curie discover 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.
How did the discovery of radioactivity change the world?
The discovery of radioactivity changed our ideas about matter and energy and of causality’s place in the universe. It led to further discoveries and to advances in instrumentation, medicine, and energy production. It increased opportunities for women in science.
Why does radioactivity kill?
It is this electron-stripping (ionising) property that does the damage to our cells and tissues. As well as generating heat, the removal of electrons can break chemical bonds. When that happens in a molecule of DNA it can cause mutations, which can lead to cancer down the track.
Where did radioactive elements come from?
For example, uranium and thorium are two radioactive elements found naturally in the Earth’s crust. Over billions of years, these two elements slowly change form and produce decay products such as radium and radon. During this process, energy is released. One form of this energy is alpha radiation.
Why was Pierre Curie coughing so much?
Unbeknownst to Pierre and Marie, handling radium is dangerous to humans and leads to a terrible cough Pierre develops and chronic anemia for Marie. In 1903, Marie shares a Nobel Prize with Pierre, making her the first woman to win the prize.
