- The definitions of the energy dose for water as a measured quantity for the entire sector of radiotherapy gives rises to practical problems when implemented for dosimetry of soft X-rays, as the flat chambers which are commonly used in this energy range cannot be applied to a water phantom. For this reason, the ionization chamber is inserted into the surface region of a solid-state phantom.
