RTwater®

Water equivalent material ideal for use in radiation therapy

OVERVIEW

  • For quality assurance measurements and for monitor calibration procedures
  • Ideal for high energy photon and electron dosimetry (MeV)
  • Can be molded into arbitrary shapes
  • Great long-term stability

 

RTwater is a proprietary material which has the same X-ray attenuation characteristics as liquid water.

It is an extremely stable, homogenous and uniform solid material and can be used for monitor calibration and quality assurance  measurements (photons, protons and heavy ions).
