Comparison between Experiment and Calculation on Induced Activities in Concrete for High Energy Heavy-Ion Accelerator Facilities

We measured activities of some kinds of aggregate of concrete irradiated by neutrons which were emitted from copper bombarded by 400MeV/nucleon neon beam. Through the gamma-ray spectrometry over a half of year, 36 radioactive nuclides were observed. Activities induced by neutrons were calculated by using the Monte Carlo simulation code NMTC/JAM, MCNP and DCHAIN-SP2001. We discussed differences between experimental results and calculated ones.
