Analyses are performed for investigations in a broad range of research
The largest class of applications concerns
radiocarbon dating such as settlements, art and religious objects in
archaeology, sedimentation and geochemistry in geology, landscape
evolution in geography. To a smaller extent 14C-analyses are
applied to trace contributions of pollutant gases in the atmosphere.
10Be are applied to
deep-sea sediments and manganese nodules to retrieve chronologies on a
million-year timescale. However, the 10Be accumulation in
sediments depends on chemical conditions of the water column, which
affects the reliability as a dating tool. In conjunction with
radiocarbon dating, which does not have this problem, 10Be is
used to trace variations in the conditions.
and 36Cl are applied to samples of bedrock and of meteorites.
For meteorites, the remaining radionuclide concentration is used to
retrieve its terrestrial age. For bedrock, the radionuclide
concentration is accumulated from exposure to cosmic rays, especially at
contribute to the development of the following applications.
Dating of mortar
mortar is dated through pieces of charcoal, presumably introduced
during production; the dates
established the chronology for the Jewish graves in Rome starting at
about 0 AD (about 300 years earlier than assumed).
Dating of human bones
complications in dating of human bones are observed
through the aging effect of about 100 years of skeletons
of historically known persons.
Tracing sea level changes
attempts are made to disentangle possible sea level changes in the
past from detailed series of radiocarbon dates of marsh plants grown in
open connection with the sea.
Dating Antarctic ice
14C in situ production in Antarctic ice is studied for
retrieval of ice dynamical parameters (accumulation rate, ablation rate)
and for establishing a correction procedure to be used for dating of
Antarctic ice with the trapped carbon dioxide.
Tracing anthropogenic pollution
the fossil origin of man-made pollutants as carbonyls is a handle to
trace their origin on the hand of air samples.
