To study the interaction of charged particles with biological living cells,we delivered 2,2.5 and 3 MeV protons outside vacuum as external beam at room temperature to irradiate yeast Pichia cells which are supported by 50 nm thick silicon nitride film and the transmission energy spectrum were measured by an Au-Si surface barrier detector to analyze energy deposition properties.The results demonstrate that the energy loss decreases with the incident protons energy increase,but the energy straggling increases with incident protons energy increase.
