Abstract

Fricke gel dosimeters allow measurements of 3D dose distributions and can be an effective tool for dosimetry verifications in radiotherapy. Various authors have reported drawbacks of the gels affecting the accuracy in case of low dose measurements. Purpose. This study aims at investigating such drawbacks and at establishing the conditions for an optimal use of the gels.
