Transmission of Beta Radiation through Shields

For most shielding problems of interest, the beta shield will be made thick enough to provide total absorption of beta particles. Some information on the range of beta particles (electrons) has already been given above (Range-Energy Relationships for electrons). The data presented in this section provides typical transmission curves for beta spectra (from radioactive decay) in aluminium. The data has been obtained with geometry for which the source, shield and detector are close to each other. Therefore counting rate rather than dose rate is given. Provided for educational interest.
