This study aims at quantifying the determinants of Vietnam’s potential exports to the EU, taking agricultural commodities as a case study. In order to achieve this, we employed a stochastic frontier analysis to estimate Vietnam’s potential agricultural exports, and a system GMM approach to analyze the determinants of the estimated potential agricultural exports of Vietnam. The results showed that Vietnam’s potential agricultural exports to the EU have been high and on an upward trend. In addition, factors such as financial market development, trade freedom, technological readiness, and labor freedom have positive impacts on Vietnam’s potential agricultural exports to the EU. Measures to improve the financial market development, remove trade barriers, increase technological capability, and promote labour freedom are strongly suggested in order to enable Vietnam’s agricultural exports to attain its maximum level.

This paper presents the development of simulated workplace neutron standard fields at the Institute for Nuclear Science and Technology with the 241Am-Be source moderated by polyethylene spheres with diameters of 15 cm and 30 cm. The characterization of the standard fields (in terms of neutron fluence rates and neutron ambient dose equivalent rates) was performed using Bonner sphere spectrometer system together with MAXED and FRUIT unfolding codes. The related quantities such as neutron dose equivalent-averaged energies and fluence-to-ambient dose equivalent conversion coefficients were also determined. The discrepancies of values are satisfied the standard uncertainty criteria as recommended by the International Standard Organization 12789 series. It implies that the simulated workplace neutron standard fields can be applied in the practical works for calibration purposes.
