first and foremost, alpha radiation is made of helium atoms that move very fast and can pass through paper, but nothing thicker. beta radiation is made up of fast moving electrons. one advantage they have is that they are so light that they can actually fly through multiple layers of plastic or even some thin amounts of metal. lastly gamma radiation are made up of photons and can penetrate sheets of lead.
2) differentiate between fission and fusion.
nuclear energy is what is produced when you do a reaction like fission or fusion. some pros are: little pollution, reliable, and somewhat safe. some cons:possible meltdowns, radiation, and waste disposal.
