TEST OF MULTIELEMENT ANALYSIS OF BONE SAMPLES USING INSTRUMENTAL NEUTRON-ACTIVATION ANALYSIS (INAA) AND ANTI-COMPTON SPECTROMETRY

INAA and anti-Compton spectrometry has been employed in the analysis o f test bone samples. Validity and accuracy of the method were checked by the use of two biological reference materials procured from the Nat ional Institute of Standards and Technology, USA (NIST) and the Intern ational Atomic Energy Agency, Austria (IAEA). NIST 1486 Bone Meal (ca. 200-800 mg) and A-11 Milk Powder (ca. 200-600 mg) samples were irradi ated in the 100 kW TRIGA Mainz reactor. Concentrations of 13 elements in both biological reference materials have been determined and were f ound in good agreement with the certified and provisional values.
