Commonly, such sources are obtained by a reactor technology (153Gd) or using an ultrastable X-ray tube with properly shaped spectrum of radiation. We suggested utilize the 179Ta isotope (Ex~ 55 keV, T1/2= 665 day) in combination with 57Co (Eγ=122 keV, T1/2=273 day). A soft technology for producing planar sealed 179Ta/57Co sources at an electron accelerator by X-ray irradiation of a target from natural tantalum and nickel was developed. The isotope yield and absorbed power of radiation in the target device vs electron beam energy were calculated using a modified transport code PENELOPE-2008. The results of experiment conducted to determine the yields of the target isotopes and by-products are in good agreement with the simulation data.
