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).
