Pergascript orange-based polymeric solution as a dosimeter for radiotherapy dosimetric validation
YS Soliman, WB Beshir, MH Abdelgawad… - Physica Medica, 2019 - Elsevier
A radiation colour former amino fluoran dye, Pergascript Orange (PGO), in a polyvinyl
butyral solution containing a colour developer, hexachloroethane (HCE), was prepared and
investigated for radiotherapy dosimetry of 60 Co, 6 MV and 15 MV photons. PGO, a
colourless dye, reacts with the acid produced upon radiation exposure of HCE, enabling the
lactone ring to open and the orange colour of PGO to develop. The ring opening of PGO was
confirmed by the appearance of a broad peak of OH− at 3360 cm− 1, Cdouble bondO …
