Abstract

The successful manufacturing of a modified Fricke gel with increased shelf life in a pilot scale (20-liter) commercial production facility is reported. The gels remained chemically stable and usable for over 30 days. Linear dose dependence was observed for cumulative doses up to 30 Gy. Dose-depth studies showed a good correlation between the experimental data and theoretical expectations, but the dose response appeared to be energy-dependent.
