|Title:||Carbon determination in human teeth by activation with He-3 ions.||Austin Authors:||Chaudhri, M A;Crawford, A C||Affiliation:||Department of Medical Physics, Austin Hospital, Melbourne, Australia||Issue Date:||12-Jul-1990||Publication information:||Biological Trace Element Research; 26-27(): 521-7||Abstract:||A nuclear analytical method, involving activation with 3He ions, was developed to determine carbon content in human teeth with well-documented histories. 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
