Glow curve calculations are presented for a system of interactive traps in which the deep trap population is an order of magnitude greater than that of the active TL traps. It is shown that the glow peak exhibits a first‐order type of kinetic behaviour even when recombination does not predominate over retrapping. Under most of the dose ranges it is the recapture by the deep traps which is responsible for this kinetic behaviour. The likely reason for the apparent dominance of first‐order kinetics appears to be the interaction between the active TL traps and the deep traps. Another important consequence of interactive kinetics is that the growth of TL intensity with dose becomes supralinear. The interactive nature of the traps thus provides an interpretation not only for the kinetic behaviour of the glow peaks but explains also their supralinearity.
