A study on interaction of alpha particles with nuclei

Author(s): Aashi Mittal
Abstract: Alpha particles react strongly with matter because they are comparatively heavy and have a charge, producing large numbers of ions per unit length of their path. As a result, they are not very penetrating. For example, 5 MeV alpha particles will only travel about 3.6 cm in air and will not penetrate an ordinary piece of paper. For the other materials the average travel distance with respect to air is approximately inversely proportional to the respective densities of each material. 5 MeV alpha particles will only travel about 4 μm in mammal tissue.
