Abstract

A new radiation dosimeter, consisting of an optically-stimulated polymer film containing a photofluorescent sensor, can serve as a routine dosimeter and radiographic imaging medium for high-dose applications in the absorbed dose range 0.1-100 kGy. The flexible, colorless, opalescent film having a uniform thickness of 0.240 (±0.005) mm or certain other films in the thickness range 0.08-0.60 mm, are available in large batches. They can be read rapidly with a simple table-top spectrofluorimeter, excitation wavelength (λ = 450 nm) and emission wavelength (λ= 670 nm), giving a type A uncertainty of dose evaluation of < ±5% at 95% confidence level. It supplies either single integrated dose readings or two-dimensional radiographic images with relatively high spatial resolution. The present work focuses on the following gamma-ray response characteristics of the System: inter: and intra-batch reproducibility, pre- and post-irradiation stability, and dependence of dose interpretations on absorbed dose rate and irradiation temperature.
