How to determine the energy of photons released in decay

Click For Summary

Discussion Overview

The discussion revolves around determining the energy of photons released during the decay of radio-isotopes, specifically tritium and plutonium-237. Participants explore the theoretical and experimental aspects of photon emission in radioactive decay processes.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the equation needed to calculate photon energy during the decay of tritium and plutonium-237.
  • Another participant asserts that there is no single equation for this calculation, suggesting that estimates can be derived from nuclear models but emphasizing that experimental results are typically more precise.
  • It is noted that tritium undergoes low-energetic beta decay, with rare photon emissions that are not expected to have high energy.
  • For plutonium-237, it is mentioned that the decay primarily occurs via electron capture, and while maximal photon energy can be calculated using energy conservation, photon emission is not guaranteed.
  • A question is raised about the effectiveness of a gamma spectrometer for detecting tritium or plutonium-237.
  • A participant responds negatively to the effectiveness of the gamma spectrometer for this purpose.
  • Further inquiry is made about alternative methods for detection, which is redirected to another thread.
  • One participant expresses concern about the safety knowledge of the original poster regarding handling radioactive materials.

Areas of Agreement / Disagreement

Participants express differing views on the methods for determining photon energy and the effectiveness of detection techniques, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

Participants highlight the limitations of theoretical models versus experimental data, as well as the complexities involved in photon emission during radioactive decay processes.

What equation would I need to use to determine the energy of photons released when radio-isotopes decay? I would like to figure out the energies of photons released when tritium and plutonium 237 decay.

There is no "equation". While it is possible to get some estimates via nuclear models, the most precise results are usually from experiments, and you can check the published material.

Note that tritium has a very low-energetic beta decay, the emission of photons is rare and those cannot have a high energy.
Pu-237 mainly decays via electron capture, you can calculate the maximal photon energy via energy conservation, but the emission of an electron is also a common result, which can but does not have to be accompanied by the emission of photons.
 
Based off of your answer, would a gamma spectrometer be an effective manner to show that H3 or Pu237 are present?
 
With that being the case, what would be a good method to do so?
 
You have a different thread about it, please continue there.

You clearly do not have the required knowledge to work with potentially radioactive material safely anyway.
