The paper describes recent progress in neutronics integral experiments in iron assemblies. The absolute activation reaction rates in an iron sphere were measured by eight kinds of activation foils. The absolute activation reaction rates at an end of iron cylinders with different thickness were measured by a set of activation foils. The leakage γ-ray spectra from the iron spheres were measured with a BC-501A scintillation spectrometer. The measured results are compared to the calculated ones.
