Abstract
Apparatus and method for electronically screening abnormal glow curves of thermoluminescenct materials such as LiF:Mg,Ti in routine dosimetry, wherein glow curves with abnormal patterns are identified by examining a few key features from which information about background and thermoluminescent (TL) signals can be extracted. By analyzing the records of quality control (QC) cards that are in the same group as field cards, dosimeter- and reader-dictated parameters, such as the peak location, are automatically determined, thus eliminating the need for any prior knowledge of those conditions required for reference determination. The apparatus and method are applicable to dose levels down to at least 50 .mu.Sv.
