"Beta radiation can be stopped by 1.25 cm of paper or a thin sheet of Perspex or aluminium 10,11. However, high atomic number materials such as lead or tungsten is ineffective at stopping the beta radiation because secondary radiations can be produced. For example, tungsten anode is used in X-ray tubes to produce X-rays from high energy electron beams 11."

"History and etymology"
"Enrico Fermi first theorised beta decay in 1933. In that year, in fact, he wrote his famous work: "Tentativo di una teoria dell'emissione dei raggi beta"; in it he transformed Pauli's qualitative hypothesis into a quantitative theory. With the article published by the magazine "Nuovo Cimento" and "Zeitschrift für Physik", Enrico Fermi proposed, in summary, the existence of a new interaction/fundamental force: the weak force 12."
