Fig. 2. Relationship between the depth of half saturation (the depth at which the luminescence signal is 50% of the saturation level) and exposure time under different parameter values. Only one of the following parameters were varied while keeping the other parameters unchanged: (a) μ, (b) $\bar{σ φ_{0}}$ , (c) $\dot{D}$ , (d) D₀.
