Absorption of Beta Particles in Different Materials: An Undergraduate Experiment
La Rocca, Paola; Riggi, Francesco
European Journal of Physics, v30 n6 p1417-1425 Nov 2009
The absorption of beta rays from a radioactive source in different materials was investigated by the use of a simple setup based on a Geiger counter and a set of absorber sheets. The number of electrons traversing the material was measured as a function of its thickness. Detailed GEANT simulations were carried out to reproduce the obtained results. This work was undertaken as an addition to the laboratory activity in an undergraduate curriculum. (Contains 6 figures.)
