Speed of alpha radiation
WebIn the case of alpha radiation, the energy The particles leave the nucleus . The alpha particle is an helium atom and contains two neutrons and two protons. It leaves the nucleus of an unstable atom at a speed of 16,000 kilometres per second, around a tenth the speed of light. WebGamma radiation is the most penetrating of the three radiations. It can easily penetrate body tissue. It requires several centimetres of lead or about 1 metre of concrete to absorb it.
