辐射

Radioactive fallout still pollutes Rongelap Atoll, about 100 miles (160 kilometers) to the east, but recent studies have found no long-term impact on marine life there.

辐射尘污染仍朗格拉普环礁约100英里（ 160公里）向东部的，但最近的研究发现，没有长远的影响，对海洋生物的存在。

In study of ICF, polystyrene hollow micro-spheres are one of the most important targets because of its low density and atomic number.

在ICF 靶丸研究中，PS空心微球是主要的靶型之一，由于PS 靶具有低密度、低原子序数，可以降低辐射驱动内爆实验过程中燃料预热及流体力学不稳定性，提高实验效率，并且有利于实验过程中诊断，所以PS 靶愈来愈受到重视并很快得以发展。

In 1922, Bohr received the Nobel Prize in physics for his work in atomic structure and radiation.
