Description

Boron in carbonate reference samples was measured by neutron-induced prompt gamma-ray analysis (PGA) using cold and thermal neutron guide beams of the JRR-3M reactor. In order to determine B contents in marine carbonates, the Doppler-broadened γ-ray peak of 478 keV was used together with the correction of interference from Na-peak of 472 keV. B in coral samples was determined within 3% of analytical precision. The data obtained by the present method are mostly consistent with reported values. PGA of B in marine carbonates is reported.
