Frolík, Jan ; Drtikolová Kaupová, S. ; Stránská, P. ; Světlík, Ivo ; Velemínský, P.
The sister of Prince Boleslav II Princess Mlada is among the persons associated with the beginning of the Prague bishopric. As the founder of the monastery of St. George was worshiped in it. The place of her burial was forgotten and searched for since the Baroque period. In this context, attention is paid to the graves JK-102 and JK-110 in the chapel of St. Anne in the monastery and also to the relics taken from this chapel in the 17th century. Grave JK-110 was newly dated to around the year 1000.

Selection of mortars samples for radiocarbon dating

Radiocarbon dating of organic residues may not always correctly determine the age of analysed historic mortars. Therefore, it seems advantageous to use of carbon dating of the carbon contained in the structure of the lime mortar, which will provide representative data of the age of the investigated structure. The methodology presents basic instructions and rules for sample selection, processing, and evaluation. The aim of this methodology is the identification of cases where the radiocarbon dating of a binder is appropriate and to define the reasons why some binder systems fail to provide relevant results.

Behaviour of radioactive substances in the Vltava and Elbe Rivers during nuclear accident

Behaviour of radioactive substances in the Vltava and Elbe Rivers during nuclear accident Ing. Eva Juranová Supervisor: Ing. Eduard Hanslík, CSc. Abstract This work is focused in the research of the behaviour of radioactive substances released into the hydrosphere of the Vltava River and the subsequent Elbe stretch during a severe accident at the Temelín Nuclear Power Plant. The background values of anthropogenic radionuclides in surface water, residual contamination after the Chernobyl accident and after atmospheric tests of nuclear weapons, were evaluated using two methods and these methods were compared. The migration of the accidental radioactive contaminants in the watercourse would be mainly influenced by their ability to sorb onto the solid phase in the hydrosphere. Therefore, the sorption of particular anthropogenic radionuclides onto bottom sediments and solids suspended in the water column was monitored and evaluated at several sites along the Vltava and the Elbe Rivers. Furthermore, the possibility of using tritium, which is discharged during normal operation of the Temelín power plant, as tracers for the purposes of modelling the migration of pollution, was assessed.
