SUMMARY

The extinction coefficient of gamma rays in the atmosphere is crucial for understanding how far they can travel before their intensity diminishes. Specifically, gamma rays with an energy of 10 MeV can penetrate significantly further than those at 1 MeV. The distance a gamma beam travels before its intensity reduces to half or to 1/e is highly dependent on the energy level of the gamma rays. Accurate calculations are necessary to determine these distances for various energy levels.

PREREQUISITES
  • Understanding of gamma ray energy levels
  • Knowledge of atmospheric physics
  • Familiarity with the concept of extinction coefficients
  • Basic principles of radiation attenuation
NEXT STEPS
  • Research the extinction coefficient of gamma rays at different energy levels
  • Study the principles of radiation attenuation in various media
  • Explore calculations for gamma ray penetration in the atmosphere
  • Investigate the impact of atmospheric conditions on gamma ray intensity
USEFUL FOR

Physicists, atmospheric scientists, radiation safety professionals, and anyone studying the behavior of gamma rays in the atmosphere.

Hi, can someone tell me the extinction coefficient of a gamma ray in the atmosphere? How far does a gamma beam go in the atmosphere before its intensity reduces to half or to 1/e?

A long time ago, when I was working, I did calculations like this, but I can't remember the results. However, one thing that is very important is that it the distances you want are very strongly dependent on the gamma ray energy. 10 Mev rays go much further than 1 Mev rays.
