Dose measurements in Witt liquid, which simulates cortical bone, have been compared with dose in water for 6‐, 9‐, 12‐, and 15‐MeV electron beams. Measurements were made using a Farmer ionization chamber. The results of the study show dose enhancement in Witt liquid of 5%, 7%, 4%, and 0.4% for 6‐, 9‐, 12‐, and 15 MeV electrons at shallow depths. The dose to a small mass of soft tissue in bone has also been estimated using ionization measurements. The results show a significantly higher dose in bone.
