2
These radionuclides undergo radioactive decay, by emitting harmful alpha particles, betaparticles or gamma rays.
它们在衰变期间会放出对人体有害的粒子粒子或射线。
3
When alpha and betaparticles strike demron , intervening electrons in the salt atoms deflect and slow them down , whereupon they are absorbed into the material.
