Dosimetric properties of various colored commercial glasses.
Brazilian commercial glasses of various colors (bronze, brown and green) have been studied to evaluate their potential as radiation-sensitive materials in gamma high-dose dosimetry. Characteristics of their optical absorption responses (reproducibility, room temperature stability, and calibration curves) have been obtained using a spectrophotometer and a simple densitometer specially designed for glass samples. The glass spectra feature a decay at room temperature that has to be taken into consideration. The results show that the colored glasses can be used in dosimetry; the upper limit of the dose range depends on the glass type.
