Experiments which activation technique was employed were carried out to study perturbation caused by irradiation samples to the CFBR -II fast burst reactor’s neutron field.Neutron spectra were measured by small sets of activation foils on the typical samples in the leakage neutron field of CFBR -II reactor.The neu-tron spectra, thermal and epithermal fluxes with samples were compared with those without samples .
