Dear Fluka experts,
I’ve simulated a 9e08 particle photon beam on a Cu target inside a hutch to measure the dose rate outside the lead shield wall. I’m trying to understand the indication of radiation just outside the hutch wall. How can I interpret this? Why have they stopped just outside the wall? Have I done something wrong in the INP file? Please help me to understand this result and fix any errors in the INP file. I’ve attached the Flair file and two images.
