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

Click For Summary
SUMMARY

Gamma rays cannot be deflected or shielded by electromagnetic fields (EMF) due to their lack of charge, which renders EMF ineffective against them. Gamma radiation originates from neutrons and high-energy photons, primarily produced during nuclear decay or annihilation processes. Effective shielding against gamma rays requires high atomic number (high-Z) materials that possess a high electron density, enabling interactions through the photoelectric effect and Compton scattering. For nuclear pulse propulsion and radiation shielding, understanding the limitations of EMF in gamma ray interaction is crucial.

PREREQUISITES
  • Understanding of gamma radiation and its sources, including nuclear decay and annihilation.
  • Knowledge of electromagnetic fields and their properties.
  • Familiarity with high atomic number (high-Z) materials and their role in radiation shielding.
  • Basic principles of photon interactions with charged particles.
NEXT STEPS
  • Research the photoelectric effect and its significance in gamma radiation shielding.
  • Study Compton scattering and its implications for high-energy photon interactions.
  • Explore the properties and applications of high-Z materials in radiation protection.
  • Investigate the principles of nuclear pulse propulsion and its challenges related to gamma radiation.
USEFUL FOR

Physicists, nuclear engineers, radiation safety professionals, and anyone involved in nuclear technology or radiation shielding strategies.

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.
