A Monte Carlo simulation framework for investigating the effect of inter-track coupling on HO productions at ultra-high dose rates
Ramin Abolfath, Sedigheh Fardirad, Houda Kacem +2
Background: Lower production of HO in water is a hallmark of ultra-high dose rate (UHDR) compared to the conventional dose rate (CDR). However, the current computational mo…
