N. L. Aluker, Ya. M. Sudzaltseva, A. N. Chernov

The dating of Quaternary deposits by means of thermo-luminescent method (TL) is concerned with a number of difficulties associated with a variety of factors influencing on the obtaining of proved datings. These factors are analyzed in the work. To assess time intervals of dating calculations of charge carriers life span under fixed temperatures at medium and high temperature traps are carried out, the dependence of termoluminescent signal accumulation in definite peaks of thermoluminescense from dose rate in dosage range up to 100 kGy is studied. As advanced option for obtaining more reliable information it is suggested to use the intensity ratio in medium and high temperature termoluminescent peaks. Registration of change trends in these ratios enables researchers to avoid mistakes during evaluation of time span.

Key words: thermoluminescense, detector, test radiation dose, dose rate, thermoluminescent dating, Quaternary deposits.
