This type of decay is called β- (beta minus) decay. A link is provided to a related question with a descriptive answer that details the process.
Radioactivity is a term that refers to the emissions from atomic nuclei due to changes in those nuclei. Those changes will occur as a result of instability of isotopes of certain elements. These atoms have a nuclear structure that is inherently unstable for whatever reason. And any unstable nucleus will eventually decay in a manner characteristic of that particular atom (radioisotope). We term the activity associated with the natural changes due to nuclear instability radioactive decay. As you can guess, different things might appear as an expression of the radioactivity of a radioisotope, and they'll vary according to the radioisotope being inspected.We could say that the elements on the upper end of the periodic table are radioactive, and these elements, the ones beginning with bismuth, have no nuclear configurations that permit them to avoid instability and their eventual radioactive decay. Additionally, we know that there are isotopes of other elements (lighter ones) that are not stable, and these radioisotopes are radioactive and will decay in time. Lastly, there are the elements technetium and promethium, which are the only elements with atomic numbers below that of bismuth that have no stable isotopes.The emissions we might gather under the umbrella of radioactivity include both particulate radiation and radiation in the form of energy, or electromagnetic radiation. Your investigation of the instabilities associated with atomic structure and what it is that results is just beginning. Use the links below to check facts and learn more.

Nuclear waste has three different types: alpha, beta and gamma. Alpha (helium nucleus) and beta (electron or positron) are subatomic particles, meaning they are pieces of atoms. Gamma is an energy wave. Gamma is the most dangerous type of radioactive waste, although all nuclear waste is potentially hazardous. When a nuclear reaction happens, pieces of atoms fly off and release the energy that held them together, producing gamma radiation as well as the energy we convert into electricity at nuclear power plants. Because nuclear waste is made up of "broken" atoms, it will require a nuclear reaction to get rid of them, essentially putting the atoms back together and reabsorbing the gamma radiation. Unfortunately, chemicals alone are not strong enough to get rid of nuclear waste. Chemicals, or rather radioactive metals, combined with a powerful "reverse" nuclear reactor may work. Scientists have been working on a solution for a few years now. Check out this article: (See related Link)
The Answers community requested more information for this question. Please edit your question to include the particular radioisotope you are asking about.
Nuclear weapons emit various types of radiation, including gamma radiation, neutron radiation, and thermal radiation. These forms of radiation can have harmful effects on living organisms and the environment.
Nuclear medicine techniques depend on detecting gamma rays emitted by the radioisotope injected into the body. The radioisotope is attached to a specific drug that targets particular organs or tissues. By monitoring the distribution of the radioisotope, healthcare providers can diagnose and treat various medical conditions.
Yes, light bulbs emit radiation in the form of visible light.
Humans emit infrared radiation, which is a type of electromagnetic radiation that is invisible to the human eye but can be felt as heat.
A nuclear reactor primarily emits electromagnetic radiation in the form of gamma rays. These gamma rays are released during the nuclear fission process that occurs in the reactor core. Additionally, reactors may also release some neutron radiation through reactions with the reactor's components.
Our sun emits mostly visible and ultra-violet radiation
Humans emit visible light in the form of infrared radiation, which is a type of electromagnetic radiation.
Bananas emit very low levels of radiation in the form of potassium-40, a naturally occurring radioactive isotope. The radiation levels from bananas are so low that they are considered safe for consumption.
Yes
Humans emit heat waves in the form of infrared radiation. This radiation is a type of electromagnetic wave that is given off by our bodies as heat energy.
