Because its not a decay process. Gamma is an emission of energy in the form of photons from the nucleus when the nucleus changes from one energy level to a lower energy level. It is true that this is often preceded by a decay event, such as alpha or beta, but it is a distinct, non decay, event.
Gamma emission is not a decay process. It is a restabilization process of the nucleus in response to some other decay process, such as alpha or beta, which leaves the nucleus in an excited state. When the nucleus comes down from that excited state it emits a photon of energy equal to the step change in energy that was made. Short answer: The atomic mass or atomic number of a nucleus is not changed, specifically, by the gamma emission, but it is changed by the precipitating alpha or beta (or other) event that left the nucleus in an excited state. Slightly more correct answer: The mass of the nucleus is decreased by the equivalent mass of the loss of energy that occurs. This ratio is e=mc2, where c2 is 9 x 1018, so you can see that the delta mass due to gamma emission is very, very small.
Gamma is not a decay process. It is a consequence of a decay process, but it, in itself, is not a decay process. It is the emission of a photon from the excited state of the nucleus in response to a decay process such as alpha or beta that changes the nucleus and leaves it with excess energy.
Radioactivity is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter. It remains unaffected by external factors like temperatures, pressure etc. It involves emission of alpha, beta and gamma particles/rays.

The reason for all types of radioactive decay is the instability of the nucleus, some unstable nuclei become stable by alpha emission and some by beta emission.
Generally this is called nuclear fission. In the special case where one of the new particles produced is a Helium-4 nucleus (2 protons, 2 neutrons) the process is radioactive decay and specifically alpha emission. (The He-4 nucleus is called an alpha particle, as it was the first such particle recognized. A beta particle is an electron emitted from the nucleus with the conversion of a neutron to a proton = beta emission.)
Is the process by which the atomic nucleus becomes slightly smaller, as a result of the emission of particles, electromagnetic radiation, or both. ELECTROMAGNETIC FORCE is the right answer
The nucleus of the atom decays, and in the process, the nucleus transforms into another element, or into an isotope or isomer of the same element. In radioactive decay, the nucleus always emits some kind of particle(s). It is the high-energy emission of these particles that we call radiation. There are many different types of radioactive decay:Alpha decay results in the emission of an alpha particle (two neutrons and two protons)Beta decay results in the emission of a beta particle (an electron or a positron)Neutron decay results in the emission of a neutronProton decay results in the emission of a protonGamma decay results in the emission of a gamma particle (a photon)Neutrino decay results in the emission of a neutrino or antineutrinoIn some cases, a combination of the above emissions takes place. For example in double beta decay, a single nucleus emits two electrons and two antineutrinos in the same event.

Cytokinesis is not the stage of mitosis. It is the process in which cytoplasm of cell splits while mitosis is a process in which nucleus of cell is splitted into two daughter nuclei.

A nucleus can be inherently unstable. It can absorb an energetic photon (photoactivation) and become unstable. It can capture positrons, electrons, neutrons, and protons and become unstable. Decay processes include: # Alpha emission, a high energy 4He nucleus # Beta emission, a high energy electron # Beta+ emission / Beta capture, either a positron is emitted or an electron is captured into the nucleus (Burp!) # Gamma emission, one or more high energy photons are emitted # Neutron emission, neutrons of varying energies may be ejected in the process of a heavy nucleus decay (even tritium).
