Various characteristics of the high temperature TL (HTTL) in the glow curve of LiF:Mg,Ti (TLD-100) are reviewed. Special emphasis is placed on the question of the linearity/supralinearity of the HTTL dose response at low dose levels from 2.5 to 250 mGy. It appears that a mild HTTL supralinearity of approximately 15-50% for each dose decade may be present between 5 and 250 mGy followed by an abrupt and rapid increase in the supralinearity above 250 mGy. However, difficulty in the estimation of background and the great variability in the protocols of measurement does not allow a definitive conclusion.
