Is it correct to calculate the number of particles

AI Thread Summary
To calculate the number of particles recorded by a detector using MCNP, the F8 tally can be employed to obtain the energy spectrum. The counts from the full energy peak should be multiplied by the number of emitted particles to determine the total counts. For a Co-60 source, which emits two photons, the normalization factor is 200, reflecting the intensity of both energies. When calculating counts for both low and high energy particles, the areas of different peaks should be multiplied by their respective percentages. The normalization factor may vary depending on the radionuclide used.

I want to calculate that how many particles will be recorded by detector with MCNP.
using the F8 tally which would provide energy spectrum, add all of data that related with full energy peak of spectrum, multiply by number of nps, then obtain the number of particles.
is it correct ? i am not sure about this.

Hi,
With this method you will calculate the number of count in your detector for one particle. After you must multiply by the number of particles emited.
For example if you have 100 Bq of Co 60 multiply F8 by 200 and you will have counts/s

Thank you ! 100 Bq of Co-60 source multiply F8 by 200 because the Co-60 source has two different energies ? what if i need to calculate both low energy and high energy counts, is it correct that multiply the areas of different peaks by 200 with different percentages of both low energy particles and high energy particles?

200 because 2 photons with 100 % in intensity
The normalisization factor depends of the radionuclides

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...
