AI Thread Summary
To model the dose in Gy from a gamma source on a surface as a function of distance in MCNP6, it's essential to determine the specific calculation needed, such as dose, kerma, dose equivalent, or equivalent dose. Various tally types, including *F4Mesh, F4, F6, and *F8, have been used in relevant literature, leading to confusion about the best choice. Users are encouraged to experiment with each tally type to see which one best meets their modeling needs. Understanding the desired output will guide the selection of the appropriate tally. Selecting the correct tally is crucial for accurate dose modeling in MCNP6.

I have a problem where I want to model the dose in Gy of a gamma source on a surface as a function of distance. In the papers I have read several different tallys have been used which leaves me a little confused as to the appropriate tally. In the papers the *F4Mesh, F4, F6, and *F8 tallys were used.

Can you tryout each one and decide from that?
 
Hi,
the first question you need to answer is "What I want calculated ?" :
- dose,
- kerma,
- dose equivalent,
- equivalent dose
 
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...
