报告摘要：
The natural radiation environment in space consists of a mixed field of high energy protons, heavy ions, electrons and alpha particles. Interplanetary travel to the International Space Station and any planned establishment of satellite colonies on other solar system implies radiation exposure to the crew and is a major concern to space agencies. With shielding, the radiation exposure level in manned space missions is likely to be chronic, low dose irradiation. Radiobiological effects of low doses of ionizing radiation are subjected to modulations by various parameters including bystander effects, adaptive response, genomic instability and genetic susceptibility of the exposed individuals. Ground based studies based on accelerator generated heavy ions such as those available at the National Institute of Radiological Sciences in Chiba, Japan provides an opportunity to target particles generated for both clinical radiotherapy as well as experimental research on space radiation biology. This lecture will provide a glimpse of the ongoing basic and clinical research under the auspices of the International Open Laboratories platform at the NIRS.
