Some nuclei, especially heavier ones, are unstable , or radioactive, emitting energy in the form of alpha rays, beta rays, or gamma rays.

有些原子核并不稳定，特别是较重的核，或称具有放射性，以α射线、β射线或γ射线的形式发出能量。

Some nuclei, especially heavier ones, are unstable, or radioactive, emit ting energy in the form of alpha rays, beta rays, or gamma rays.

I think the mechanism is possible: We all know that by the atomic nucleus and its nuclear spin around the outside of electronic components, electronic itself have a spin.

我认为可能的机制是：我们都知道原子是由原子核和核外绕其旋转的电子组成，电子本身也产生自旋。
