Shielding and activation experiments with secondary particles from the aluminum beam dump with water coolant irradiated by 2-11 GeV electron beam at JLAB in USA. Several kinds of activation detectors were installed into the 3 irradiation pipes located inside the shield downstream from the dump. Production rates of radionuclides were estimated through radio-activity measurement. Monte Carlo simulations were performed and attenuation profiles in the shield were compared with the experiment results.
