AI Thread Summary
To determine dose rate using MCNP6, it's essential to multiply tally results by the photon yield or intensity. The photon yield varies by radionuclide, with specific examples given for Co-60 and Cs-137. For Co-60, the yield is two photons at 1.33 and 1.17 MeV per Bq, while Cs-137 has an intensity of 85% for 662 keV. Relevant yield data can be found on dedicated websites, such as nucleide.org. Accessing these resources is crucial for accurate dose rate calculations.

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

Thank you so much for that link its exactly what I was looking for!
 
Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information(power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.) for Material 2 is zero, while Material 1...
Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
