Beta radiation consist of small particles (electrons) with an incredible speed, Alpharadiation 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 radiation data involved detecting low levels of gamma radiation and suspected alpha/beta particulates in air.
辐射数据包括探测低水平的微克辐射和可疑的alpha/beta微粒。

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.
