Water equivalent RW3 Slab Phantom with chamber adapter plates for radiation therapy dosimetry.

Slab Phantom

The Sun Nuclear RW3 Slab Phantom is designed for high

energy radiation therapy dosimetry from Co-60 to 25 MV

photons and from 4 MeV to 25 MeV electrons.

The phantom consists of 33 RW3 plates with dimensions of

30cm x 30cm. By combining plates of different thicknesses,

measurements can be made in 1mm increments up to a

depth of 30cm.Features

Suitable for high energy photon and electron

dosimetry.

Enables user to perform quality control of absolute

and relative dose measurements.

Allows user to vary the measuring depth up to 30cm

in increments of 1mm.

Made of water equivalent RW3 material (Goettingen

White Water) with thickness tolerance of ± 0.05mm.

Adapter plates for various detector types can be

inserted without air gaps.
