- TL;DR Summary
- Higher average energy after passing through lead

Hello,

I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere in my calculations, but I've checked and re-checked to the upteenth time and can't find any errors. I'll attach my python code below. Appreciate any assistance because I'm literally going crazy.

Thanks
