Recent related research examples (II) Irradiation experiment (2.5 GeV) at PHERF in Pohang Accelerator Laboratory (S. Korea) to study activation of environmental samples and benchmark FLUKA Monte Carlo intra-nuclear cascade code. Analysis is under way. Further experiments seem necessary to better understand possible FLUKA underestimation of 3 H generation as well as of some other radio-isotopes 18 ESTB Workshop 2011, March 17, 2011
