This the decay (disintegration) rate.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Isotopes that emit particles and give off energy are known as "radioactive" isotopes. The particles they emit generally come in the form of α-radiation i.e α particles (helium nucleus), and ß-radiation, i.e. ß-particles (electron or positron). Some small amount of neutrons may be emitted by an isotope as a byproduct of α-radiation. The primary energy emitted by radioactive isotopes is gamma radiation and heat; the heat comes from the effect of α-, ß and gamma radiation being absorbed by the surrounding materials.
Radioactive minerals are unstable and emit radiation at a constant rate. They also have half lives and lose energy overtime. Nonradioactive minerals are stable, and by there own are incapable of emitting energy.
All radioactive isotopes are unstable and they decay to a stable isotope emitting particles.
Atoms with unstable nuclei that undergo radioactive decay to transform into another atom are called radioactive isotopes or radioisotopes. These isotopes emit radiation in the form of particles or electromagnetic waves as they decay. This process can result in the formation of different elements or isotopes, depending on the type of decay.
These isotopes are unstable and emit radiation.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.

During fission, atoms split into smaller fragments, releasing energy and neutrons. Some of these fragments are radioactive isotopes, which emit radiation and decay over time, creating radioactive waste.

Isotopes are radioactive because they have an unstable nucleus, which means they have an imbalance of protons and neutrons. This imbalance causes the nucleus to emit radiation in the form of alpha particles, beta particles, or gamma rays. Factors that contribute to their ability to emit radiation include the number of protons and neutrons in the nucleus, as well as the energy levels of the particles within the nucleus.

A radioactive isotope is an unstable atom which emit radiations as alpha, beta, gamma, neutrons, positrons etc.
They emit particles, electromagnetic radiation, or both.* Apex*
Some isotopes emit an electron on decay, others emit a positron (anti-electron).
