B Prevalence of nuclear decays accompanied by gamma emission

Click For Summary
Many alpha and beta decays result in an excited daughter nucleus that emits gamma rays to achieve a stable ground state. Notable examples include the beta decay of Co-60 and Na-24, where gamma emission is documented for cobalt but not for sodium. The discussion raises the question of whether gamma emission is common in most isotopes, suggesting that it may not be explicitly mentioned in decay tables due to its prevalence. Overall, gamma emission is a frequent occurrence in nuclear decays. This indicates a general expectation that part of the decay energy will be released as gamma radiation.

Some alpha or beta decays produce an excited daughter nucleus, which typically immediately emits one or more gama rays to reach a ground state. This is the case for beta decay of Co-60 or Na-24 for example. While the table of cobalt isotopes on Wikipedia mentions the gamma emission, the one for sodium does not. Do most isotopes decay by modes accompanied by the gamma (so we do not bother mentioning it in the tables and tacitly expect part of the decay energy to be emitted as gamma), or is it rather rare?

Thread 'Some confusion with the Binding Energy graph of atoms'

My question is about the following graph: I keep on reading that fusing atoms up until Fe-56 doesn’t cost energy and only releases binding energy. However, I understood that fusing atoms also require energy to overcome the positive charges of the protons. Where does that energy go after fusion? Does it go into the mass of the newly fused atom, escape as heat or is the released binding energy shown in the graph actually the net energy after subtracting the required fusion energy? I...
