Preliminary feasibility study of congo red dye as a secondary dosimeter

Degradation of Methyl Orange and Congo Red dyes by using TiO2 nanoparticles activated by the solar and the solar-like radiation

“…CR is used in medicine as a biological stain and as an indicator since it turns from red-brown in a basic medium to blue in an acidic one (Coleman, 2006). It can also be used as a secondary gamma-ray dosimeter since its coloration decays with the intensity of radiation (Parwate et al, 2007). Therefore, the effective decolorization of dye-containing wastewater is an important and challenging task that must be approached.…”

Radiation induced degradation of dyes—An overview

“…• H is generally associated with the reversible reductive decolonization, and the radicals • OH and • HO 2 /O 2− are considered to be the cause of the reversible oxidative decolonization.Besides these few examples on the use of dyes as chemical dosimeters, there are many other citations available in the literature on this topic[72][73][74][75][76][77][78].…”

A Study on Dosimetric Characterization of Direct Yellow 12 Dye at High Radiation γ-Dose

“…Determination of the absorbed energy is carried out by a dosimeter. 1 The dosimeters usually comprise of the chemicals that respond linearly to radiation under prevalent conditions. Many rare-earths, alkaline earth metal compounds are conveniently used as a dosimeter, because various changes occur in thermo luminescence and other optical properties due to the reaction with ionizing radiations.…”
