# How are confinement and radioactive decay both possible?

I have a question regarding how to reconcile the observation of confinement and nuclear decay (without further hadronization).

Let's assume that the nucleus is a proton emitter and nucleon 1 (N1) is the proton which is emitted in the radioactive decay. How is it possible that the red quark in N1 does not interact with the green/blue quark in N2, N3, ... ? Especially if one takes into account that the coupling constant of strong interaction is actually larger at larger distances?

I suspect it has something to do with the orders of magnitude of the relevant quantities involved (energy or resolution, e.g. nuclear: $10^{-15}$m and particle $10^{-18}$m), but I am looking for a more detailed answer.
