RW3 Slab Phantom

Water-equivalent RW3 slab phantom with chamber adaptation plates for therapy dosimetry

The RW3 phantom is water-equivalent in the energy ranges  from 60Co to 25  MV photons  and  from 4 MeV to 25 MeV electrons. The  phantom is used for monitor calibration and quality assurance  measurements. Depth dose measurements are made by varying the measuring depth. To provide for  backscatter, slabs are placed below the radiation detector. The  slab  phantom  consists  of  1  plate 1 mm  thick, 2 plates  each 2 mm  thick, 1 plate 5 mm thick and 29 plates each 10 mm thick. This combination makes it possible to vary the measuring depth inincrements of 1 mm. The size of the complete phantom is 30 cm x 30 cm x 30 cm. Adapter plates for a number of detector types are available for both phantoms.
Each plate is precisely machined for a thickness tolerance of only ± 0.1 mm.

  • Makes it possible to perform monitor calibrations and depth dose measurements in a solid state phantom
  • Suitable for high energy photon and electron dosimetry
  • Makes it possible to vary the measuring depth up to 30 cm in increments of 1 mm
  • Made of water-equivalent RW3 material (Goettingen White Water) with thickness tolerance of ± 0.1 mm
