Luminescence dating of Somero sacristy, SW Finland using the 210 degrees CTL peak of quartz

The 210 degreesC thermoluminescence (TL) peak of quartz, extracted from bri ck fragments of Somero sacristy (Finland), which were partly elements of co nstruction, were used for the measurement of archaeological dose for the pu rpose of dating. The annual gamma dose-rate with cosmic component and beta dose rate of bricks were measured using two types of TLD detectors (AL(2)O( 3)-C) inserted in situ and in laboratory, respectively, The improvements in the precision of the TL measurements, components of annual dose assessment are described, and the results of TL age determination are discussed and c ompared with the archaeologically expected age.
