Temperature response for the Harwell Red 4034 Perspex® dosimeter

Synthesis of a flexible poly(chloroprene)/methyl red film dosimeter using an environment-benign shear compounding method

“…Similar findings were reported earlier for other polymer/ dye dosimetric systems Biramontri and Haneda, 1996;Galante et al, 2004;Kattan et al, 2011;Mai et al, 2008;McLaughlin, 2003;Meiner et al, 2004;Soliman and AbdelFattah, 2013;Tu et al, 2009;Whittaker and Watts, 2001). It is worth noting that the glass transition temperature of the used polymer lies in the sub-room temperature range ( $ À50°C); therefore, macromolecular dynamics are unlikely to experience any profound changes in the temperature range of the study (Dubey et al, 2009(Dubey et al, , 2012.…”

“…In all such radiation applications, radiation dosimetry is mandatory because precise and easy measurements of radiation doses are essential for obtaining products with desired properties. However, many of the dosimeters available today are expensive, difficult-to-use, rigid, or require hazardous air pollutants (HAPs) and volatile organic solvents (VOCs) in their manufacturing (Biramontri and Haneda, 1996;Devic, 2011;Dubey et al, 2006;Galante and Campos, 2006;Meiner et al, 2004;Whittaker, 1993). Therefore, there is a need to develop inexpensive, flexible, reliable radiation dosimeters by a solvent-free process.…”

“…Al Zahrany et al (2011) used polyvinyl butyral (PVB) films dyed with MR as radiation dosimeters, while Barakat et al used MR-doped poly(methyl methacrylate) (PMMA) in such applications (Barakat et al, 2001;Russo et al, 2002a). Although the results were promising, the used procedures of the dosimeter manufacturing were complex and involved solvents (Ajji, 2006;Al Zahrany et al, 2011;Dubey et al, 2011Dubey et al, , 2012Dubey et al, , 2013McLaughlin, 2003;Meiner et al, 2004;Russo et al, 2002b;Tu et al, 2009;Whittaker, 1993;Whittaker et al, 1997).…”
