Radioactivation Analysis of Manganese by Counting Deuterium Photoneutrons
-
S. Amiel
Summary
A method is described for the assay of 2.58 hour 56Mn in different radioactive samples by counting photoneutrons. The high energy portion of the gamma radiation of seMn, produced upon neutron activation of samples containing manganese, causes emission of photoneutrons from a D2O reservoir incorporated in a 4π neutron counting assembly. To cause photoneutron emission from D2O the gamma ray energy must exceed 2.23 MeV and thus the method discriminates efficiently against all gamma rays of lower energies. The photoneutron activity is proportional to the 56Mn content of the sample, and submilligram quantities of manganese have been analysed with a precision of ~ 1%. Sensitivities of ~ 1 /μg and better are indicated. The only serious sources of interference are sodium and fissionable elements, when present in large proportions. The method is rapid and can be used to analyse manganese in complex matrices, without any chemical processing. The neutron counting apparatus required is relatively cheap, simple and versatile.
