Easy dosimetry implementation



Absolutely homogeneous RW3 material has been developed for high-energy photon- and electron irradiation. This therefore guarantees reliable measurement in any position – and obviously, also in the case of repeat measurements.


With the variety of positioning options offered by the plates themselves, and the vast range of adapter plates for detectors, EASY SLAB is flexible enough to adapt to the required measurement. Two phantom sizes supplement the options.


Carry out routine tasks not just reliably, but quickly thanks to the simple and convenient handling. The phantom is supplied in a coffer case for easy transport and storage.
