Radioactive decay is a natural process that occurs because a given atomic nucleus is unstable. The instability in the nucleus will eventually result in some kind of nuclear change (depending on the atom), and we call this radioactive or nuclear decay. Different radionuclides undergo different types of decay that include spontaneous fission, alpha decay and beta decay. Each of these is explained in separate questions, and they already have modestly good answers. You'll find links to those questions below, as well as links to some other Related questions.
What else can I help you with?
When do radioactive isotopes occur?
A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
Is oxygen radioadive?
Some oxygen isotopes are radioactive, but they do not occur naturally.
How many times emission occur in radioactive series?
around ten 10
How does a nuclear disaster occur?
A nuclear disaster may occur when the radioactive materials are mishandled and which may lead to radioactive exposure or a chain reaction of nuclear fission, fusion. Most of these disasters are induced by the man made mistakes.
Why are most elements radioactive?
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
Which element is radioactive and synthetic?
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
Is nobelium radioactive?
Yes, nobelium is radioactive. It is a synthetic element that does not occur naturally and is produced in laboratory settings. All isotopes of nobelium are radioactive and have short half-lives, making them highly unstable.
Does all radioactive substances are manmade or artificial?
Radioactive elements both occur in nature (Uranium is the prime example) and are made through the works of man (Plutonium is man-made).
Radioactive decay can be affected by what?
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.
Does a radioisotope of gold occur naturally?
No, gold has only one naturally occurring isotope and it is non-radioactive.
Where does decay and radiation occur?
Decay and radiation occur at the atomic level within unstable nuclei of atoms. Decay is the process where an unstable nucleus emits particles or energy to become more stable, while radiation refers to the particles or energy emitted during this process. Both decay and radiation can occur in natural radioactive elements or in artificially created radioactive isotopes.
What has more radioactive decay older or younger rock?
Older rocks typically have undergone more radioactive decay compared to younger rocks, as they have had more time for the decay process to occur. This results in older rocks having lower levels of certain radioactive isotopes and higher levels of daughter isotopes which are products of radioactive decay.
