Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, beta, and gamma radiation, but there are several other varieties of radioactive decay.
Radioactive decay rates are normally stated in terms of their half-lives, and the half-life of a given nuclear species is related to its radiation risk. The different types of radioactivity lead to different decay paths which transmute the nuclei into other chemical elements. Examining the amounts of the decay products makes possible radioactive dating.
Radiation from nuclear sources is distributed equally in all directions, obeying the inverse square law.

How did Becquerel discovered radioactivity discovered radioactivity?
he noticed the first effects of radioactivity while he observed that with exposure to the sunlight the mineral gave off a penetrating energy that could expose film.
What are examples of radioactivity?
For example natural and artificial radioactivity.
What are radioactivity?
Radioactivity was discovered by Henry Becquerel but the term 'Radioactivity' was given by Madam Curie. It is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter.
Where does most of the radioactivity that you personally encounter come from?
The radioactivity that people encounter on a regular basis actually comes from their natural environment rather than the radioactivity being from some manmade source.
Who was credited was the discovery of radioactivity?
Henri Becquerel was a French scientist who was credited for the discovery of radioactivity. He was credited in 1896.
Is radioactivity caused due to unstable nucleus?
Yes.
Radioactivity is caused due to what?
spontaneous decay of unstable atomic nuclei.
Radioactivity is casued due to?
spontaneous disintegration of atomic nuclei
Who showed that radioactivity is caused by the breakdown of one atom into another?
Ernest Rutherford
What is the source of radio activiy?
Radioactivity is caused by unstable atoms, that break apart.
How does radioactivity fit into the idea of causality?
The radioactivity is caused by the the instability of several atomic nuclei; and this instability comes from the ratio protons/neutrons in the nucleus.
Radioactivity was discovered by Albert Einstein.?
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.

Where does the element californium come from?
It is a man-made element and, due to its high radioactivity does not exist in nature.
Did Marie Curie commit suicide?
No, Marie Curie did not commit suicide. She passed away in 1934 due to aplastic anemia, which was likely caused by her prolonged exposure to radiation in her research on radioactivity.
Who discovered radioactivity and how was it discovered?
I thought Marie Curie had something to do with it because she died from lukimeia which was caused from her being exposed to it :)
What has heat flow got to do with radioactivity?
The primal heat from the deep interior of the Earth is mainly due to radioactive decay, with a small contribution due to gravity compression.
