Transport methods for energetic particles 1 first-author 2 KRUG Life Sciences, Houston, TX 77058, USA KRUG Life Sciences, Houston, TX 77058, USA NASA Johnson Space Center, Houston, TX 77058, USA NASA Johnson Space Center, Houston, TX 77058, USA In order to estimate radiation risk assessment for astronaut's radiation safety in space activities, transport codes for high energy particles have been created. Two of the transport methods, perturbation and Green function methods, for high energy particles are reviewed in this paper, and some of the calculated results with the perturbation method are presented. Finally, the low energy transport in the regard of the biological effects by low energy ions is also briefly discussed Energetic particles Transport codes Radiation safety Biological effect References Wilson J W , Townsend L W , Schimmerling W et al .
