The collision will stop the particle going through the material. They move incredibly fast, perhaps thousands of kilometres per second. The more radiation passes through a matter, the greater is its penetration power. The transonic regime begins when first zones of M > 1 flow appear around the object. Beta-particles, being less ionising than alpha-particles, can travel through many centimetres or even metres or air and through millimetres of skin or tissue. In air, beta particles can travel a few hundred times farther than alpha particles. 55. They travel farther in air than alpha particles, but can be stopped by a layer of clothing or by a thin layer of a substance such as aluminum.
