The K-shell electrons have a good probability of being close to the nucleus (remember that at the quantum level, particles are described by probability waves). This allows a good cross section for the interaction of the electron and a proton to produce a neutron and a neutrino.

The definition of "forbidden" is not so absolute in quantum mechanics. As has been said above, the orbitals of these electrons are probabilities. With some of the orbitals, there is a non-zero probability that an electron can get close enough to the nucleus to be captured.

One mode of radioactive decay is through K electron capture. This occurs when the nucleus of an atom absorbs an electron in the lowest quantum level, changing a proton into a neutron.
A powerful radiation is good enough to rupture atomic structure n extract electron fm it!

the nucleus is positely charged and keeps the electron close. they can't get in the nucleus because of subatomic particles. electron capture occurs because something has the power to rip electrons from valence shells or beyond.
