Geochemistry / Assay


Samples are encapsulated and irradiated in a nuclear reactor. After a suitable decay samples are measured for their emitted gamma ray fingerprint on a germanium detector. INAA is very good for Au, Co, As, Sb, W, Ta, U, Th, Cs, In, Re, Cl  and lower levels of REE. 

A special variation of reactor based  method called delayed neutron counting (DNC) is used for uranium assay.

Boron is also determined by a special type of reactor based method called prompt gamma analysis. 

INAA when combined with Nickel sulphide fire assay is used for the platinum group metal assay.
