    What Could Be Causing Unexpected Results in the LET Analysis with MCNP6.2?

    Actually, I wanted to generate the LET from secondary electrons produced by this photon source. Although there are other analyses available, I came across this tool in the manual and wanted to test it. However, I encountered a problem. Since this tool is not commonly used, I was hoping to find...

    What Could Be Causing Unexpected Results in the LET Analysis with MCNP6.2?

    Hey guys, first, thank you for your response and greetings. Second, to simplify the analysis of the problem, I inserted a small water sphere less than 2 cm away from the Ir-192 source. I used this tally to calculate the LET. The observed behavior is consistent: it is counted in the smallest...

    What Could Be Causing Unexpected Results in the LET Analysis with MCNP6.2?

    I'm dealing with a specific situation: I'm analyzing Linear Energy Transfer (LET) in a cylindrical sample. According to the definition of LET in the manual, we have: “The linear energy transfer (LET) special tally option allows track length tallies to record flux as a function of stopping power...
