Glow curve evaluation in routine personal dosimetry.
The glow curve of LiF:Mg, Ti (TLD-100) has a well known and defined shape. Several factors, however, can distort the glow curve shape and can lead to incorrect dosimetry. Only proper evaluation of glow curves, either by visual inspection or computerized method, can detect these anomalies. Visual observation is riot only tedious and time consuming but may also be susceptible to human errors. The usefulness of a commercially available glow curve analysis software during quality control testing of thermoluminescence dosimetry cards is discussed. The long-term stability of the thermoluminescence dosimetry reader is also investigated using this software. Various types of glow curve anomalies encountered during routine personal dosimetry practice are presented.
