Abstract: A dosimeter product that simplifies the process of dosimetry in medical diagnosis, therapy and other fields where high precision is needed. The dosimeter product is obtained by a unique training method which stabilizes the sensitivity of the dosimeter. Stability in sensitivity is established by a combination of high temperature cyclical annealing and low temperature furnace annealing. After the sensitivity of the dosimeters is stabilized, the dosimeters are then calibrated by generating for every dosimeter within a group element correction coefficients (ECCs) that compensate for the differences in sensitivity among the group of the dosimeters, bringing the sensitivity of each dosimeter to the sensitivity of the mean of the population. The result is a group of precalibrated dosimeters with stable sensitivity that are ready to use with established correction factors for individual TL response differences.

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.
