This is an example of the Weak force, and is fairly rare.Electron capture requires that there be an electron in the vicinity of the nucleus, so its activity depends strongly on the configuration of the electron cloud, which depends on the chemical state.The effect of this on alpha decay, which is the most common decay mode in radiometric dating, is utterly insignificant.
The major reason that decay rates can change is that the electric field, from the atom's electron cloud, can change due to chemical changes.In the case of carbon dating, it is not the initial quantity that is important, but the initial ratio of C, but the same principle otherwise applies.Recognizing this problem, scientists try to focus on rocks that do not contain the decay product originally.As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.The energy locked in the nucleus is enormous, but cannot be released easily.

The phenomenon we know as heat is simply the jiggling around of atoms and their components, so in principle a high enough temperature could cause the components of the core to break out.
