Abstract
The density (g cm-3) and electron density (cm-3) of material from the anterior chest wall was determined. On the average, the difference in density between rib bone and intercostal soft tissue amounted to 17 per cent, while the difference in electron density was 7 per cent. The attenuation of high-energy electrons in specimens of rib bone, costal cartilage and sternum was determined by an experimental technique, using dosimeters of TLD material. The results of determinations of attenuation of 10 and 13 MeV electrons in fresh specimens are presented. It is concluded that electron radiation in the energy range of 10 to 13 MeV can be utilized for irradiation of lymph glands along the internal thoracic vessels without risk of underdosage.Keywords
