Abstract

In this work, recent results about the dependence of the response of poly(vinyl-alcohol)-glutaraldehyde Fricke gel dosimeters on the irradiation and holding temperatures are reported. The investigations were carried out by two complementary techniques commonly used in gel dosimetry, namely spectrophotometry and MRI. No significant dependence of the dosimeters sensitivity on the irradiation temperature in the range 20 ◦C–35 ◦C was observed. On the contrary, the holding temperature effects resulted to be not negligible. This work, based on literature results, highlights the limits and the capability of these dosimeters in the 3D dose mapping for clinical practice applications
