Now, we're going to say in terms of size, we know that the alpha particles are the largest radioactive particle. So, we're going to say beta particles therefore are smaller than alpha particles. Now, because they're smaller in size, they're gonna be less damaging if we ingest them. So here, they're gonna have a lower ionizing power. But the problem here is because they're smaller, they're able to better penetrate into our skin. So, here they're going to have more penetrating power. And so, to stop, you need a sheet of metal or large block of wood to make sure a beta particle does not enter inside of our bodies.
