| Abstract: | Active BCG-PEG radiochromic liquid system has
been formulated for potential application as threshold dosimeter for gamma
radiation that can be visually evaluated. PEG concentrations have been varied
to see their effect on the radiation sensitivity of these systems. The response
characteristics are monitored both visually and by UV-Vis spectrometry. The minimum visually detectable level
achieved with the formulated solution is 0.2 kGy, where the solution showed a
sharp colour change from green to yellow. The detection level could be moved to
the higher side by increasing the concentration of PEG in the formulation.
Preliminary dose dependence studies have been carried out in the range 0.3-7.5
kGy/hr. |
