What is the difference between radioactivity and radiation? Radiation is the energy or particles that are released during radioactive decay. The radioactivity of a material refers to the rate at which it emits radiation.
What is the meaning of radioactivity?
Definition of radioactivity : the property possessed by some elements (such as uranium) or isotopes (such as carbon 14) of spontaneously emitting energetic particles (such as electrons or alpha particles) by the disintegration of their atomic nuclei also : the rays emitted.
What is radioactive decay in simple terms?
Definition of radioactive decay a radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.
What is produced by the radioactive decay?
The emissions of the most common forms of spontaneous radioactive decay are the alpha (α) particle, the beta (β) particle, the gamma (γ) ray, and the neutrino. The alpha particle is actually the nucleus of a helium-4 atom, with two positive charges 42He. Such charged atoms are called ions.
What are the types of radioactive decay?
A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles.
What is radioactive decay in Kid words?
Radioactive decay is a term used to describe the changes in an atom once it has become unstable and begins to lose its particles.
What is radioactive decay give example?
As per the quantum theory, it is not possible to predict whether a given atom will undergo radioactive decay or nuclear disintegration. Common examples of radioactive decay include alpha decay, proton emission, double proton emission, beta decay, electron capture, and neutron emission. 4.5 (1)
What is the importance of radioactive decay?
Radioactive decay is very important for a wide range of human activities, from medicine to electricity production and beyond, and also to astronomers.
What are the uses of radioactive decay?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
What are some examples of radioactivity?
The following radioactive elements are found naturally in the environment.

- Uranium. Uranium is a radioactive element that can be found in soil, air, water, rocks, plants and food. …
