Development of Converged and Integrated Application Technologies using Neutron Activation Analysis

○ Establishment of analytical system using cold neutron PGAA/NDP and implementation of PGI measurement basis - Background reduction(1/10) by the development of anti-coincidence counting technique and the development of TOF-PGAA system - Evaluation of measurement capability of CN-PGAA system(B : < 0.1 ppm) - Enhancement of spectroscopy system for Neutron Depth Profile(NDP) - Evaluation of detection limit and analytical capability for major elements using NDP(depth resolution : 37 nm) - Monte Carlo simulation for the optimum design of PGI system - Development of PGI algorithm ○ Development of application technologies using integrated NAA - Analytical accuracy of reference materials using CN-PGAA : < 10% - Analysis of 20 elements such as major and rare earth elements in archaeological samples by NAA : accuracy < 15% - Establishment of provenance study for domestic stone heritage NAA - Study of correlation between elements in serum and blood pressure and blood sugar from normal person and dementia patient.
