alpha radiation

基本解释

Radon gas escapes easily from the ground into the air and emits heavily ionizing radiation called alpha particles.
氡气很容易从地下释放到空气中并发射出称为阿尔法粒子的强致电离辐射。
If radioactive material is ingested or inhaled into the body, however, it is actually the lower energy alpha and beta radiation that becomes the more dangerous.
然而，如果人体摄取或吸入放射性材料，低能的α和β粒子更为危险。

Beta radiation consist of small particles (electrons) with an incredible speed, Alpha radiation consists of big particles (two protons, two neutrons altogether), also with incredible speed.
贝塔是高速冲击的微小粒子（电子），阿尔法辐射是高速冲击的大粒子（含有两个质子和两个中子）。

On the other hand, when it came to penetrating solids, penetrating solids, the alpha radiation was poor at penetrating solids, whereas the beta radiation was very good at penetrating solids.
另一方面，当研究穿过固体的时候，嗯，穿过固体，会发现阿尔法射线很难穿过固体，然而贝塔射线,很容易穿过固体。

About 10 to 15 years later, another physicist, Ernest Rutherford, actually put this plum pudding model to test, Ernest Rutherford and he did it through studies that he'd been doing on radiation that was emitting something called alpha particles.
因此我们要，在上面再做改进,大概过了10到15年，另外一个物理学家,用实验来检测这个李子布丁模型,他一直从事alpha粒子辐射研究。

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.
