Fusion energy without strong nuclear radiation

Conventional quantum mechanics calculation shows that fusion energy without strong nuclear radiation is feasible, because this is the nature of sub-barrier nuclear fusion. When the Coulomb barrier is relatively thin and low, the resonant tunneling would select the fusion reaction with strong neutron and Gamma radiation. On the other hand. if the Coulomb barrier is thick and high, the resonant tunneling would select the fusion reaction without strong neutron and Gamma radiation. Thus, fusion energy with lowest radiation is predictable in terms of d + t fusion data. This is the harmony between various approaches towards fusion energy. What we lose is the assumption of compound nucleus model for light nuclei fusion, and what we gain is the fusion energy without strong neutron and Gamma radiation.
