BlueWater Slabs

Blue Water

BlueWater is a fast, easy-to-set-up alternative to traditional water tanks for routine checks of a linear accelerator's photon beam.

A New Standard in Water Equivalency

  • BlueWater is a water equivalent material within 1.0% for photons, and is free of contaminants and air

  • Slabs from this unique material are exceptionally strong and will not stick together when stacked or stored

  • BlueWater is not affected by changes in temperature or humidity

Unique Ion Chamber Slab Design

In slabs that are at least 2 cm thick, cavities are available to accommodate parallel plate ion chambers or thimble type ion chambers. Instead of having multiple slabs for each thimble type ion chamber, a single ion chamber slab is used with interchangeable ion chamber plugs.

Tested for Consistency

Each production run of BlueWater is tested at an independent calibration laboratory for consistency

Wide Range

  • Blue Water is available in nine standard thicknesses
  • Custom phantom sizes and shapes are available upon request
