The possibility is shown and the sensitivity of detecting microobjects in the radiography of thick steel objects using microfocus (13 μm) bremsstrahlung of a new source based on a betatron with an electron energy of 18 MeV is evaluated. The image contrast and resolution of a pair of thin (48 μm) Duplex IQI wires are demonstrated, which is the basis for determining the sensitivity of microobject detection. Keywords: betatron, electron beam, bremsstrahlung, radiography.
