In my universe, radioactive decay involves a change in the nucleus of an atom, often releasing alpha or beta particles, or gamma rays. Sometimes neutrons are released, and occasionally, spontaneous fission occurs.
How does it work in your universe?
Pressure does not have a significant effect on the rate of radioactive decay, as it is mainly influenced by the instability of the nucleus of the atom. The decay process is determined by the nuclear forces within the atom, which are not significantly affected by external pressure changes.

It helps keep the Earth's interior hot.
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
For all practical purposes, No. However, there is a very small effect on some elements due to pressure (E.g. http://www.sciencemag.org/cgi/content/abstract/181/4105/1164), there is a small effect upon Beta Decay due to magnetic field strength, and there is an effect due to ionization.
If it is related to Nuclear studies, then the answer would be fusion.
I am not quite sure what you mean, but radioactive isotopes such as carbon-14 will have the same radioactive properties - i.e., they will decay - anywhere in the Universe, not just on Earth. In general, the laws of nature are believed to be the same everywhere.
Uranium undergoes radioactive decay and emits alpha particles which can damage tissue.
Decay energy is the energy that has been freed during radioactive decay. When radioactive decay is ongoing it drops off some energy by means of discharging radiation.
One reason is that radioactive decay heats the earths interior
That statement is not entirely accurate. Radioactive decay can involve the emission of alpha particles, beta particles (electrons or positrons), and gamma rays. Electrons can be involved in certain types of radioactive decay processes.
