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)。
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。
