Application of neutron activation analysis to control P2O5 content in ore and ore concentrates of ''Apatit'' works

A technique for a neutron activation rapid analysis of fluorine is described. A mean-square error of the analysis makes up 0,g3 per cent F. The investigation has been carried out and a close correlation has been established for the Hibine massif exploited apatite deposits on the basis of the neutron activation analysis of fluorine and chemical analysis of P2O5. Possibilities are shown of using the neutron activation analysis of P2O5 in ores and certain ore con-- centrates of ''Apatit'' works from the radioactivity induced in fluorine. A mean-square error of the analysis makes up 0,35 per cent P2O5
