Answer:
Nuclear forces :affects the rate at which a radioactive material decay.
Step-by-step explanation:
Radioactive decay in which is not stable atomic nucleus release energy, by emitting alpha, beta particle.
The nuclear force is the force present between the neutrons and protons of the atoms.
Nuclear forces affect the radioactive material decays.
The weak interaction which is called weak nuclear force is the process which results in the interaction among the subatomic molecules which affect a radioactive material decays.
Thus by this mechanism, Nuclear forces affect the radioactive material decays.
