国际空间站（ISS）计划进行许多空间实验。国际空间站的建成将很快成为现实。宇航员将暴露于空间辐射的低水平背景成分，包括重离子和其他高线性能量转移（LET）辐射。为了长期留在太空，我们必须保护人类健康免受太空辐射的影响。与此同时，我们应当认识到空间辐射的最大允许剂量。近年来，对空间辐射的物理监测每天检测到约1毫希。这个数值几乎是地球表面的150倍。然而，空间辐射对人类健康的直接影响目前尚不清楚。因此，在长期飞行中进行生物剂量学测量以计算相对生物有效性（RBE）对人体健康具有重要意义。RBE可能因微重力而改变。为了了解精确的RBE和与微重力的任何相互作用，国际空间站离心系统将是一个关键工具，希望该系统将尽快投入运行。
Many space experiments are scheduled for the International Space Station (ISS). Completion of the ISS will soon become a reality. Astronauts will be exposed to low-level background components from space radiation including heavy ions and other high-linear energy transfer (LET) radiation. For long-term stay in space, we have to protect human health from space radiation. At the same time, we should recognize the maximum permissible doses of space radiation. In recent years, physical monitoring of space radiation has detected about 1 mSv per day. This value is almost 150 times higher than that on the surface of the Earth. However, the direct effects of space radiation on human health are currently unknown. Therefore, it is important to measure biological dosimetry to calculate relative biological effectiveness (RBE) for human health during long-term flight. The RBE is possibly modified by microgravity. In order to understand the exact RBE and any interaction with microgravity, the ISS centrifugation system will be a critical tool, and it is hoped that this system will be in operation as soon as possible.
