説明
We improved procedures to analyze boron contents in volcanic rocks by using neutroninduced prompt γ-ray. The improvements include: (1) calculation of boron peak area only for the high energy half portion to avoid sodium peak overlap effect, (2) increase of sample weight by using pressed powdered pellets to save irradiation time, and (3) correction of count rate fluctuations and effect of sample geometry using silicon as an internal standard. Precisions of the 3-4 determinations of boron in GSJ (Geological Survey of Japan) volcanic standard rocks were less than 9 %. Our boron analyses agree well with the recommended values.
