Two competing channels which produce γ-rays:  (n,γ) and  (n,f) For fissile materials:  (n,f)  5 ·  (n,γ) → 10 times more γ-rays We have to distinguish the γ-rays from neutron capture from the γ-rays produced in the (n,f) reactions. Solution: measure the fission γ-ray background in coincidence with micromegas fission detectors. Successful test on 235 U performed in Real measurements have to follow.
