It is, therefore, important to estimate radiation risk in human body of high-energy & charged (HZE) particles, especially secondary scattered radiation field produced by the interaction between heavy ions and structural materials of a space station etc.In this study we designed an experimental field for chronically low-dose irradiation of secondary radiation scattered with heavy-ion radiation field and examined cellular responses in the field.}, pages = {306--311}, publisher = {Institute for Environmental Science}, title = {Reduction in life span on normal human fibroblasts exposed to low-dose radiation in heavy-ion radiation field.}, year = {2003} }
