Abstract The Bremsstrahlung exposure rate from beta point source, probability of energy loss by beta during the Bremsstrahlung emission and the Bremsstrahlung activity of tissues have been calculated. The Bremsstrahlung yield for tissues in the wide energy range is also estimated from 0.01 to 100 MeV using the tabulated values given for elements by Lucien pages. The estimated Bremsstrahlung activities of pure beta nuclides in all types of tissues are extremely large (10 2 –10 6 GBq). The patients receiving such nuclides would never receive that much activity because of prohibitive radiation toxicity (few 100 MBq). Thus the patients receiving these pure beta emitting nuclides do not have to be hospitalized for radiation precautions.
