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。
As radon progeny decay, they emit radioactive alpha particles and attach to aerosols, dust and other particles in the air.
阿尔法粒子是氦核,它们是放射性衰变的产物。
Alpha particles are these helium nuclei, and they are the result of radioactive decay.
我们发现的第一种衰变方式——阿尔法衰变——是放射性粒子产生氦分子!
The first type discovered -- alpha decay -- is when a radioactive particle emits a Helium nucleus !
Alpha particles are these helium nuclei, and they are the result of radioactive decay.
