Applications of pixe-pige in philately

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1990
Abstract Several postage stamps dating back to the 1890's from the Republic of Taiwan were irradiated with an external 4.0 MeV proton beam to simultaneously induce X-ray and gamma ray emission. The paper and printing inks were compared between stamps made from different dies.

PIGE analysis of magnesium and beryllium

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2010
Abstract In this work, we present an alternative method for PIGE analysis of magnesium and beryllium in thick samples. This method is based on the ERYA – Emitted Radiation Yield Analysis – code, which integrates the nuclear reaction excitation function along the depth of the sample.

PIGE analysis and profiling of aluminium

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2008
Abstract In this work we present an alternative method for PIGE analysis of aluminium in thick samples. This method is based on the ERYA – emitted radiation yield analysis – code, which integrates the nuclear reaction excitation function along the depth of the sample.

The sensitivity of the PIGE analytical technique

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2007
The aim of this work is to provide a basis for the estimation of fluorine and lithium contributions to the background of gamma-ray spectra and of their influence on PIGE (Proton-Induced Gamma-Ray Emission) detection limits of lithium, boron, fluorine and sodium.

Determination of13C in breath sample by PIGE

Journal of Radioanalytical and Nuclear Chemistry Articles, 1991
This paper discusses a novel application of PIGE for the determination of13C in breath. Samples of human breath, urea, glucose, benzamide, barium carbonate were analyzed against cylinder CO2 and graphite standard. An accuracy check of the13C determination (with reference to mass spectrometric “True” results) gave a relative error of only −0.4% for PIGE.
