Abstract
Particle-induced gamma-ray emission (PIGE), which measures prompt gamma rays at 428 keV from 10B (p, p'γ) 7Be, was used to confirm the boron distribution within 2hr-BPA-exposed cells. Distribution images of potassium, phosphate, and boron and the whole spectrum showed the ratios of boron counts to total (%) as follows: control group: 1.35 ± 0.073%; 2hr boron exposure group: 2.33 ± 0.35%; and boron exposure/wash group: 1.58 ± 0.095%. Micro-beam PIXE/PIGE can be a promising tool for visualization of intracellular Boron.
