Remember that opposite charges attract, so if you were to fire all three particles through an electric or magnetic field the alpha particles would deflect towards the cathode, the beta particles to the anode and of course the gamma would pass straight through without a care in the world. When radiation collides with molecules in living cells it can damage them. If the DNA in the nucleus of a cell is damaged, the cell may become cancerous. The cell then goes out of control, divides rapidly and causes serious health problems. Very high doses of radiation can kill the cell completely, which can cause radiation poisoning. If you accidentally swallow some radiation, as you do, then you better hope it’s not alpha, because they are the biggest particles and are easily absorbed by living cells. Beta and gamma radiation are not as dangerous because they are less likely to come into contact with your cells as they are so tiny and will most probably pass straight out of you. On the other hand if someone throws a piece of radioactive material at you, the big alpha particles wouldn’t penetrate as easily because they are too big. Beta and gamma however would pass straight through you and cause damage.\n
