First of all, the majority of the alpha particles were transmitted through the screen, OK, majority, vast majority.
第一点，大部分的阿尔法粒子，全都从屏幕穿透过去了，嗯，大部分的，绝大部分的。
As radon progeny decay, they emit radioactive alpha particles and attach to aerosols, dust and other particles in the air.
氡子核在衰变时发射出放射性阿尔法粒子，这些粒子可附着于空气中的浮质、灰尘及其它粒子。
In the paper a personnel neutron dosimeter based on a CR-39 plastic track detector registering heavy recoils and alpha particles is described.
本文叙述了一种用于测量中子剂量的“直接相互作用”型的CR - 39塑料反冲径迹个人中子剂量计。
As we breathe, radon progeny are deposited on the cells lining the airways where the alpha particles can damage DNA and potentially cause lung cancer.
当我们呼吸时，氡子核可堆积在呼吸道壁层的细胞上，而阿尔法粒子可破坏DNA并有可能引起肺癌。
As a result, radon progeny may be deposited on the cells lining the airways where the alpha particles can damage the DNA and potentially cause lung cancer.
结果，氡子核可堆积在呼吸道壁层的细胞上，而阿尔法粒子可破坏DNA并有可能引起肺癌。
If he switched from gold to let's say iron, he also tried platinum, a number of different foils, he found that they count rate it still was 20 alpha particles per minute.
金箔的时候，计数率就变成零了，如果他把金换成比如说铁，他们还尝试了铂，还有一系列其他的箔片，他发现计数率还是每分钟。
So, what he could conclude thus far was that this was really consistent with the Plum Pudding model. All of his heavily-charged alpha particles were going right through this thin layer of gold atoms.
和布丁模型是吻合的，所有的重alpha粒子，都穿过金原子，你们也许会觉得，他可以就此。
Experiments conducted in its ALPHA laboratory found a way of using strong, complex magnetic fields and a vacuum to capture and hold the mirror-image particles apart from ordinary matter.
在ALPHA实验室进行的实验发现了一种使用复合强磁场和真空来使镜像粒子和普通物质分离开的方法。
