Alpha particles are not the only kind of radiation! There are also beta particles and gamma rays! ๐
Alpha particles are big, heavy, and positively charged. They donโt travel far and can be stopped by paper or the skin. In contrast, beta particles are lighter and can travel further, being stopped by plastic or
aluminum. Gamma rays, however, are super tiny and can go through almost anything, including humans! ๐ก
Understanding these differences helps scientists know how to protect us from harmful radiation and use it for good things, like medicine!
