Abstract
A short-lived, delayed neutron activation technique has been investiga ted to determine the content of cryolite (Na3AlF6) in core samples, by the detection of fluorine through the fast neutron reaction F-19(n, a lpha)N-16. The resultant gamma-rays in the energy range of 2.84-8.14 M eV measured for pure cryolite and background samples, established that cryolite concentrations > 13.6 wt% in rock samples could be estimated with uncertainties of about +/-4.3 wt%. The results are very satisfac tory for exploration purposes.
