【 摘 要 】
For the neutron radiography facility renovation plan at Thai Research Reactor, mixed barite-concrete blocks of different compositions were tested for their photon and neutron radiation attenuation properties.60Co and137Cs isotopes were used as the gamma sources;241Am-Be was used as the neutron source. For detection, a scintillation counter and a BF3tube were used. The intensities at various energies were measured and attenuation coefficients were calculated. Samples of barite mixture were analyzed with X-ray. The results involving the effects of barite are reported and discussed.
