Extensive fade study of Harshaw LiF TLD materials

A comprehensive and extensive fade study was conducted for Harshaw LiF TLD materials. This study covers the well-established LiF:Mg,Ti and LiF:Mg,Cu,P materials in their different isotopes, sizes, forms and time–temperature readout schemes. Two parts of the fade study on the signal loss and the sensitivity loss were carried out in a long-term period of 500+500+ days at temperatures of 0, 20 and 40∘C using more than 3500 dosemeters. Detailed results are presented and a summary is provided.
