SUMMARY

The discussion focuses on obtaining photon yield or intensity values for MCNP6 simulations, specifically for calculating dose rates. Users highlighted that the yield depends on the radionuclide, with examples provided for Co-60 and Cs-137. Co-60 emits two photons at 1.33 and 1.17 MeV, resulting in 2E9 g/s for 1 GBq, while Cs-137 has an intensity of 85% for 662 keV, yielding 8.5E8 g/s for the same activity. The data can be found on the Nucleide website, which offers comprehensive tables for various isotopes.

PREREQUISITES
  • Understanding of MCNP6 simulation software
  • Knowledge of radionuclide decay and photon emission
  • Familiarity with dose rate calculations
  • Access to nuclear data resources, such as the Nucleide database
NEXT STEPS
  • Research MCNP6 output file formats and data interpretation

I am working on a problem determining dose rate using MCNP6. I am following two papers that did the same type of simulation and in them they multiply the tally results by the photon yield also called the photon intensity to detrime the dose rate. My question is where does one find this value ? Is it in the output file or are there tables of yield for different isotopes? Thanks in advance.

Hi
the yield dépends of your radionuclide.
For example Co-60 emits two photons 1.33 and 1.17 MeV for one Bq so for 1 GBq it emits 2E9 g/s.
For Cs-137 the intensity is 85 % for 662 keV so for 1 GBq it emits 8.5E8 g/s
you can have, for example, this data on the site : http://www.nucleide.org/Laraweb/index.php
