论文摘要
相对论火箭板上的辐射危险可能是内部和外部的。由于其特异性最高的能量密度，反物质被认为是加速多吨火箭到相对论速度的首选火箭燃料。物质抗灭绝物的高能产物（γ-光子和介子辐射）可能会对机组人员和电子产品产生严重的辐射危害。可以反对我们对恒星追求的另一个因素是，迎面而来的核子辐射是由星际气体和宇宙射线的相对论逆风而产生的，其强度随火箭速度而增加。当火箭加速到相对论速度时，中性和电离原子和分子的稀疏星际气体会转变为高能核子的迎面而来的通量，从而辐射了火箭体并造成了严重的辐射危险。相对论尘埃颗粒的即将到来的助焊剂对火箭尸体造成了机械损害的威胁。
Radiation hazard on board of a relativistic rocket can be of internal and external origin. Because of its highest specific energy density, antimatter is considered to be the preferred rocket fuel for accelerating a multi-ton rocket up to relativistic speed. High-energy products of matter-antimatter annihilation (gamma-photons and meson radiation) can produce a severe radiation hazard for crew and electronics. Another factor that can stand against our pursuit to the stars is intense nucleons radiation produced by the oncoming relativistic headwind of interstellar gas and cosmic rays with their intensity increasing with rocket velocity. When a rocket accelerates to a relativistic speed, the rarefied interstellar gas of neutral and ionized atoms and molecules transforms into the oncoming flux of high-energy nucleons irradiating the rocket body and creating the severe radiation hazard. The oncoming flux of relativistic dust granules imposes a threat of mechanical damage to the rocket body.
