The pretreatment of non-cremated bone samples starts with the extraction of collagen, which is the material that is dated.One way to reduce this problem is to combine AMS with the detection of characteristic projectile X-rays.After analysis in the AMS system, the ions are stopped in a suitable target and it is possible to identify the ions by atomic number and thereby separate the isobars.Antlers – Chunks, chips, and shavings are best for radiocarbon dating.If your samples are already powderized, please contact us for discussion.We may not be able to provide d15N measurements for charred or heated bones depending on the sample quality. Beta Analytic also provides %C, %N, C: N and % collagen yield at no additional cost for non-cremated bones submitted for AMS dating.

The % collagen yield test is performed on a small sub-sample of the submitted bone.

Bones – Good cortical bone is best from the larger bones of the body (femur, tibia, upper arm bone, jaw, skull plate and sometimes the ribs).

Spongy bones like ball and sockets, vertebra, and the like do not tend to preserve well in harsh conditions and may not yield sufficient collagen for AMS dating.

Additional fee is charged for collagen or bone carbonate extraction.

The d13C and d15N ratios are measured using an isotope ratio mass spectrometer (IRMS).

The work started in the summer of the year 2000 by Emilian Alexandrescu, archaeologist at the Institute of Archaeology 'Vasile Parvan' in Bucharest, and Agata Olariu, physicist at the Institute of Physics and Nuclear Engineering, Bucharest, when samples were taken: one sample of bone from the skull from Cioclovina, belonging to the Faculty of Geology, Bucharest, (Academician professor Neagu, and samples from the scapula and tibia remains from Muierii cave, Baia de Fier, from the Institute of Speology (Next year, in 2001 we collected samples again from Cioclovina and Baia de Fier and we could report the radiocarbon ages of Ciolcovina and Baia de Fier human remains according to the bulletin issued on the date Another skull was found in Cioclovina cave, near commune Bosorod, Hunedoara county in Transylvania, found by a worker at the exploitation of phosphate deposits, in the year 1941.
