heal.abstract	In the present work, the determination of Be concentration in soil, asphalt and concrete samples using several IBA (ion beam analysis) techniques (PIGE - particle induced gamma-ray emission, and NRA - nuclear reaction analysis/charged-particle spectroscopy) is presented. The samples originated from various areas of the former airport of Athens that is now closed to be used as an Olympic site. The main characteristic. of the samples analyzed is their complex matrix consisting of light elements in high concentrations. For such matrices, the implementation of a deuteron beam at energies between 1 and 2.1 MeV, via the Be-9(d, ngamma)B-10 reaction, seems to be the most sensitive among the applied IBA techniques. A HP Ge detector of 20% relative efficiency was used to detect the 718 keV gamma-ray of B-10. The absolute gamma-ray yield of the Be-9(d,ngamma)B-10 reaction is presented and an attempt is made in order to evaluate the applicability of PIGE in the determination of trace Be quantities in complex matrices. The results are compared to existing literature data obtained with other IBA techniques (e.g. heavy-ion spectroscopy). (C) 2004 Elsevier B.V. All rights reserved.	en
