Abstract
The con-centrations of Ca, P, Cl, Na, Sr, Zn, Br, Mn, W, Cu and Au have been studied in supragingival dental calculus. The samples have been neutron-irradiated for 20 hrs.in a flux of 1.7 x 1012 neutrons/cm2/sec. After chemical group separation of activated elements in the calculus samples by means of short ion exchangers coupled in series, gamma-ray spectrometric analysis followed.
