The rate of decay of a radioactive element cannot be influenced by any physical or chemical change. It is a rather constant phenomenon that appears to be independent of all others. The rate of decay is given by an element's half life, which is the amount of time for approximately half of the atoms to decay.
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.
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
To fully explain radioactive decay you need quantum mechanics.
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.
No, radioactive decay isn't affected by anything - temperature or pressure because it isn't a chemical or physical reaction.

No, radioactive decay is not affected by temperature, at least, not in anything like a normal range. At millions of degrees, yes, it would speed up.

Radioactive decay may or may not involve electrons. There are different types of radioactive decay.

The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
when an isotope is it does not undergo radioactive decay
It stays the same. Temperature has no effect on the rate of nuclear decay.
In reality, and what you will be taught in a standard physics textbook, is that radioactive decay is not affected by external conditions. However, theoretically, if the temperature is around 100GeV (giga electron volts), then the weak force will be unified with the strong force and the electromagnetic forces, meaning it will no longer be "weak" and the rate of decay will thus increase dramatically.
