Benkő L., Bognár-Kutzián L: Investigation of frosty and shiny quartz separates: relevance to the inclusion dating = Radiation Protection Dosimetry 47 (1993) 665. An extensive project has been initiated with the aim of dating a number of prehistoric archaeological sites in the Carpathian Basin. A new technique was introduced, which reduces the proportion of the grains exhibiting undesired TL properties, improves the sample-to-sample reproducibility of the TL response, and Results in archaeologically acceptable ages.

Some 50 TL dates representing the period from the Early Neolithic to the Late Bronze Age are discussed.

В.: TL dating of Early Neolithic pottery sherds found in the Slatina region, Bulgaria = Proc. Xllth IUPPS Congress, Bratislava (1993) 114 The paper reports on the first Results of TL dating performed in the Institute for Nuclear Research and Nuclear Energy, Sofia. Results obtained by the fine grain technique and the quartz inclusion technique are discussed. Csapó J., Költő L., Pap I.: Archaeological Age determination based on the Racemization and Epimerization of amino acids = In M. Járó, L. Költő eds.: Archeometrical Research in Hungary. National Centre of Museums, Budapest (1988) 89-102. The authors have adapted a procedure for determining the ages of fossils, using the method of isoleucine and other protein amino acid racemizations. By measuring D-alloisoleucine bone samples over 50000 years, by the fast Racemization amino acid D and L versions, followed by ion exchange column-chromatography separation-with chiral silica gel layer the ages of bone finds between 5000 and 50000 years could be determined with the error of the analytical method (for D-alloisoleucine ±5%, and ±15-20 % for the other amino acids). A proposal is made for determining bone samples with the approximate Age of 1000 years, with the possible application of amino acids with sulphur and with fatty acids. 276
