The authors have combined thermoluminescent and spectrophotometric methods to measure doses in the range 1 x 10/sup -4/ to 6 x 10/sup 5/ Gy with DTG-4 detectors of diameter 5 mm and thickness 1 mm. We used a /sup 60/Co or /sup 137/Cs source (doses 10/sup -4/-10 Gy), as well as an MRKh-..gamma..-20 apparatus (doses of 10/sup 2/-6 x 10/sup 5/ Gy). The gamma doses were monitored with a set of ionization chambers in the VA-J-18 apparatus as well as with ferrous sulfate dosemeters. The light sum was recorded over the range 20-200/sup 0/C with a Harshaw model 2000-D instrument and with a KDT-1. The optical absorption spectra were measured with an SF-26 spectrophotometer over the range 200-600 nm. The detectors were irradiated in batches of five for each dose in plastic cassettes providing obedience to the electron-equilibrium conditions.
