Various aspects of the technique of TL dating using fine grains are discussed. Nonradiation-induced TL can be reduced by taking the glow-curve in an atmosphere of O₂-free N₂. U and Th contents are measured by alpha-counting as sealed and unsealed samples in order to give a measure of the amount of emanation of ²²²Rn and ²²⁰Rn from the samples. Fine grain sample preparation is described. Beta and alpha TL sensitivities are measured by exposing fine-grain samples to known doses of ⁹⁰Sr and²¹⁰PO and responses to gamma rays is assumed to be the same as to beta rays. Included are results of studies of the relationship of the energy spectrum of the alpha par ticles to the induced TL; of the effect of ground water on the natural dose rate; and of the effect of radon emanation on the natural dose rate. The dating procedure and a discussion of results are given. -- AATA
