Abstract
The beam of high-energy Ar ions available at the Lawrence Berkeley Laboratory (BEVALAC) was used. In preparation for radiobiological studies. Depth doses were measured with a homogeneous tissue-equivalent ionization chamber which traversed the central axis of a tissue-equivalent liquid phantom irradiated by a large, uniform beam of ions. Ancillary measurements showed that for this beam the depth dose profiles measured in a water phantom and in a tissue-equivalent liquid phantom were essentially the same, provided that the difference in the electron densities of the liquids is taken into account; the depth dose profile measured behind a water absorber was essentially the same as that measured within a water phantom; and reliable dosimetry for tissue was performed using air instead of tissue-equivalent gas in the cavity of a tissue-equivalent plastic ionization chamber.
