For the study of radiation effects in rock salt caused by highly radioactive waste in potential repository sites, it is essential that dosimetry can be carried out at high doses and high irradiation temperatures. Radiation induced colour centres in LiF crystals are shown to be appropriate for the assessment of gamma doses up to at least 50 MGy at irradiation temperatures up to 250°C. The irradiations were performed at 50°C, 100°C, 150°C, 200°C and 250°C under calibration conditions in a gamma cell irradiator using a specially designed oven. The effect of the irradiation temperature on the dose response and shape of optical spectra of LiF is investigated. A method is described that allows for the estimation of the irradiation temperature. The experiments are designed to be used at the HAW project in the Asse salt mine, Braunschweig, FRG.
