Measurement of neutron attenuation length in concrete shield using bismuth and aluminum activation detectors
was performed at a shielding experiment with 24 GeV protons at CERN/CHARM. Monte Carlo simulations with a simple slab gemeotry using the PHITS code was also performed and obtained neutron attenuation length was compared with the measured results.
