Prevalence of nuclear decays accompanied by gamma emission

Click For Summary
SUMMARY

Gamma emission is a common occurrence in nuclear decays, particularly following alpha or beta decays that produce excited daughter nuclei. For instance, the beta decay of Co-60 and Na-24 typically results in the emission of gamma rays as the daughter nucleus transitions to its ground state. While the Wikipedia table for cobalt isotopes acknowledges gamma emission, the sodium isotopes table does not, suggesting a potential oversight in documenting this phenomenon. Overall, gamma emission is prevalent in most nuclear decay processes.

PREREQUISITES
  • Understanding of nuclear decay processes, including alpha and beta decay.
  • Familiarity with excited states of nuclei and their transitions to ground states.
  • Knowledge of gamma radiation and its role in nuclear physics.
  • Ability to interpret nuclear decay tables and charts, such as those provided by IAEA.
NEXT STEPS
  • Research the specific decay processes of isotopes like Co-60 and Na-24.
  • Explore the role of gamma emission in various nuclear decay modes.
  • Investigate the documentation practices for nuclear decay tables and the significance of gamma emission.
  • Examine the IAEA's V Chart for comprehensive data on nuclear isotopes and their decay characteristics.
USEFUL FOR

Nuclear physicists, radiation safety professionals, and students studying nuclear decay processes will benefit from this discussion.

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?
