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.
What else can I help you with?
How did Becquerel discovered radioactivity discovered radioactivity?
Henri Becquerel discovered radioactivity in 1896 while conducting experiments with uranium salts. He accidentally found that photographic plates wrapped in black paper near a sample of uranium salts became fogged, indicating the emission of radiation from the uranium. This unexpected discovery led to further research and the development of the concept of radioactivity.
The form of radioactivity that penetrates matter most easily is?
gamma radiationA2 perhaps neutrons.
Can radioactivity be canceled?
No, radioactivity cannot be canceled. Radioactivity is a natural process where unstable atomic nuclei release energy in the form of radiation. While the rate of radioactivity can decrease over time as the unstable nuclei decay, the process itself cannot be canceled.
What is the name of a scientist studies radioactivity?
A scientist who studies radioactivity is called a nuclear physicist or a radiologist.
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.
How did Marie and currie die?
Marie Curie died in 1934 due to aplastic anemia caused by her prolonged exposure to radiation from her research work on radioactivity.
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.
Radioactivity is casued due to?
spontaneous disintegration of atomic nuclei
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.
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 :)
Did Marie Curie commit suicide?
No, I don't think she did. I guess she died of old age.
Where does the element californium come from?
It is a man-made element and, due to its high radioactivity does not exist in nature.
What causes radioactivity?
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.
