spontaneous decay of unstable atomic nuclei.
Yes.
Marie Curie died in 1934 due to aplastic anemia caused by her prolonged exposure to radiation from her research work on radioactivity.
Ernest Rutherford
Radioactivity is caused by unstable atoms, that break apart.
spontaneous disintegration of atomic nuclei
The radioactivity is caused by the the instability of several atomic nuclei; and this instability comes from the ratio protons/neutrons in the nucleus.
No, it was discovered by Marie and Pierre Curie. Other scientists also contributed, such as Henri Bequerel. (Bequerel is the S.I unit for radioactivity). No, Marie Curie discovered and named radioactivity. Sadly her research into radiation caused her death.
I thought Marie Curie had something to do with it because she died from lukimeia which was caused from her being exposed to it :)
It is a man-made element and, due to its high radioactivity does not exist in nature.
No, I don't think she did. I guess she died of old age.
Radioactivity is caused by the instability of an atom's nucleus. An unstable nucleus can emit particles or energy in the form of radiation in order to become more stable. This process is known as radioactive decay.
She died from anemia, a condition that can be caused by exposure to radioactivity. Although it is impossible to say with absolute certainty that her work with radioactive elements caused the death, the connection is pretty strong.
