Can gamma rays be deflected or shielded against with an electromagnetic field?

Click For Summary

Discussion Overview

The discussion revolves around the potential for electromagnetic fields (EMF) to deflect or shield against gamma rays, particularly in the context of nuclear reactions and radiation protection. Participants explore theoretical interactions, practical applications, and the nature of gamma radiation.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants question whether an EMF could protect against gamma rays, suggesting that while EMF can contain plasma, its effectiveness against gamma radiation is limited.
  • One participant asserts that gamma radiation originates from neutrons, which are uncharged, implying that EMF would not significantly affect gamma rays.
  • Another participant explains that while gamma rays can interact with charged particles, they are not deterred by electric or magnetic fields, and emphasizes the role of high-Z materials in effective radiation shielding.
  • There is a mention of gamma rays being high-energy photons produced during nuclear or subatomic processes, further complicating the interaction with EMF.

Areas of Agreement / Disagreement

Participants generally disagree on the effectiveness of EMF in shielding against gamma rays, with some asserting that it has minimal impact while others explore the theoretical aspects of interaction.

Contextual Notes

Participants highlight the complexity of gamma radiation sources and interactions, noting that assumptions about the nature of gamma rays and their interactions with EMF may vary. The discussion includes references to specific physical processes and materials relevant to radiation shielding.

I know we can contain the energy/plasma from a fussion reaction with an electromagnetic field, but would an EMF protect from gamma rays? Would it be possible to deflect a nuclear blast with a powerful enough EMF?

No. While theory predicts some interaction, this is extremely small. You won't change gamma rays in any significant way with electromagnetic fields.
 
Gamma radiation is from neutrons - they have no charge so the electromotive forces of the EMF have no effect on the gamma rays. The gamma waves could impart an electrical or magnetic effect on the EMF but it would be more like the inductance of an aluminum wire passing through a magnetic field but less intense.

Thanks! It was in respect to nuclear pulse propulsion and shielding from the blast/radiation effects.
 
How about a "plasma"? Contain the plasma in a megnetic field but how the density of the plasma or its charge can shield against Gamma ray's.

One source of Gamma rays is from the NUCLEUS during radioactive decay. But it is by no means the only source of Gamma radiation.
Dont forget Gamma rays are just extremely high energy photons

Gamma rays are high energy photon keV and above from nuclear or subatomic processes, e.g., anihilation (e+e- → γγ) or decay (e.g., πo → γγ).

Photons interact with charged particles, e.g., electrons, positrons, protons, and nuclei.

Gamma rays will not be detered by electric or magnetic fields, but they will interact with charged particles within those fields.

In radiation shielding, particular for shielding against gamma rays, one would use high Z materials because high-Z means high electron density. Electrons interact with photons via the photoelectric effect or Compton scattering. In the case of nuclei, gamma rays of energy greater than 1.022 MeV initiate pair production, and at higher energies, photoneutron emission, photodissociation (d+γ → p + n) or photofission/spallation.
