The goal of this work is to measure the rate of energy loss (stopping power) of alpha particles emitted from 241Am source as it passes through hydrogen gas which have been investigated using surface barrier detector in vacuum chamber. It was found that the loss energy of alpha particles in hydrogen gas decreases linearly with the increase in the pressure between 0 and 1 bar. The measured value of the range and stopping power were compared with SRIM code and ICRU. The predicted values based on the experimental, SRIM code and ICRU show good agreement with for stopping power and rang of alpha particle.
