The first purpose of this research was improvement of sensitivity of the normoxic acrylamide-
based polymer gel dosimeter. Another aim of this study was investigation of the absorbance …

Purpose In previous studies, methylthymol-blue and benzoic acid have been introduced as
a diffuser limiter and sensitivity enhancer in the gel dosimeter composition, respectively. This …

The conventional ferrous xylenol orange (XO) gel (FXG) dosimeter is being wildly
investigated for radiotherapy dose measurements. Upon irradiation, its color turns red due to …

This paper reports the preliminary results obtained by Electron Paramagnetic Resonance
(EPR) measurements on films of IRGANOX® 1076 phenols with and without low content …

Radiotherapy widely uses the polymer gel dosimeter. The advantage of polymer gel
dosimetry is the mapped 3D absorbed dose distribution that other dosimeters cannot …

In gel dosimetry applied to radiotherapy, the space–time corrections are necessary due to
the diffusion of ions in the oxidized solution dosimetry. Consequently, methodologies are …

The accuracy and precision are necessary factors in radiotherapy, especially for
measurements involving output factors and beam profiles; in this case multileaf collimators …

In radiation therapy, the shielding of normal tissue can be made using Cerrobend® blocks or
a multileaf collimator. In this work, profiles of shielded fields collimated by Cerrobend blocks …

In photodynamic therapy, a beam of incident light on the target causes interactions with the
photosensitizing agent in the patient, subsequently killing cancerous cells through chemical …

Ninhydrin reacts with alanine forming a Ruhemann's purple (RP) compound. RP and chloral
hydrate (CH) were introduced into gelatin to form a tissue equivalent RP gel for radiation …
