RESUMEN

Quantitative neutron capture radiography (QNCR) of 10B found in pre-dried maize samples has been conducted. Calibration standards constructed from filter paper mimicked plant tissues to reduce confounding matrix effects. A mathematical track elimination method improves the LOD as well as the visual contrast image at low boron concentration levels. The LOD for total boron is 1.7 µg/g in a 4 mm2 region of interest (ROI). The w(B) in five individual maize tassel meristems has been determined to be 14.9 µg/g - 21.2 µg/g.
