Lithium diborate glass for high-dose dosimetry using the UV-Vis and FTIR spectrophotometry techniques

Glass has been used in radiation dosimetry mainly for its linear response with absorbed dose, low cost and easy evaluation. The lithium diborate glasses were irradiated with doses from 200 Gy to 10 kGy using a60Co Gamma-Cell system 220 and evaluated with the UV-Vis and FTIR techniques. The results indicate that the samples present lithium diborate, linearity with the absorbed dose, usefulness as YES/NO radiation detectors (due to their color change), low fading for time periods up to 60 days and a good response reproducibility. In conclusion, the lithium diborate glass may be promising for dosimetry in high doses of radiation.
