The most damaging radiation are gamma rays and x-rays; energetic alpha rays (streams of helium nuclei) and beta rays (electrons) can also damage cells.

最具破坏力的辐射是伽马射线和X射线；能量强大的阿尔法射线（氦核能量流）和贝塔射线（电子流）也可以破坏细胞组织。

So, introduction, "in order to explain the results of experiments on scattering of alpha rays by matter, Professor Rutherford," and there is a footnote to the Rutherford model.

嗯，绪论，为了解释实验的结果,关于物质的alpha散射，卢瑟福说“,这儿有一个卢瑟福模型的脚注。

The researches are concerned with alpha rays.

这些研究是关于阿尔法射线的。

For, as Rutherford has shown the assumption of the existence of nuclei, as those in question seems to be necessary in order to account for the results of the experiments on large angle scattering of the alpha rays.

因此卢瑟福,提出了原子核存在的假设，这些关于问题的假设对于,解释阿尔法粒子的,大角度散射是有必要的。

The Alpha Magnetic Spectrometer was designed to search for dark matter by collecting high energy radiation known as cosmic rays, and then sort through it looking for a certain class of particle believed to be created after two bits of dark matter collide in space and destroy each other.
