The tooth samples were irradiated with 2.7-MeV3He particles at 50 nA intensity, and the activity of 14O induced through the reaction 12C(3He, n)14O, determined by counting the 2.31-MeV gammas. Different dental hard tissues were studied separately. A solid piece of silver steel, the carbon content of which was accurately determined by chemical means, was used as the standard. The carbon content in different teeth varied from 4-7%. The overall experimental accuracy was better than 4.5%. | Gov't Doc #: | 1704758 | URI: | http://ahro.austin.org.au/austinjspui/handle/1/10251 | Journal: | Biological trace element research | URL: | https://pubmed.ncbi.nlm.nih.gov/1704758 | Type: | Journal Article | Subjects: | Activation Analysis.methods Adolescent Carbon.analysis.standards Child Helium Humans Isotopes Reference Standards Tooth.chemistry |
