When a radioactive isotope of an element releases a radiation particle the sub-atomic structure of it's nucleus changes. If an alpha particle is released the nucleus loses 2 protons and 2 neutrons, making it a new, lighter and smaller atom and therefore a different element. If a beta particle is released one of the neutrons in the nucleus releases an electron and becomes a proton so the atom's mass does not change significantly but t does become a different element.
everywhere, from the center of the core to the top of the atmosphere there are radioisotopes of some element
Not sure what you mean; but if there are radioactive isotopes in Earth's crust, they will decay over time, just like anywhere else.
everywhere
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
To fully explain radioactive decay you need quantum mechanics.
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
One reason is that radioactive decay heats the earths interior
Radioactive decay
Yes. That is what causes some of the Earths core heat. Elements being formed by radioactive decay. Look at the Earths' makeup and see that the percentages of elements follows the periodic chart by decay.

It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
yes, to a certain extend. The rock is cooled by the thermal extraction. It will slowly warm up again from radioactive decay (fission) in the earths core and crust.
Decay of radioactive elements in the mantle heats it.
You can also say that they are radioactive.
