Bremsstrahlung beams of a betatron with energy lower than 10 MeV are successfully used in X-ray and γ-ray introscopy for recognition of groups of materials according to their atomic number [1], for a digital diagnostics in medicine [2] and etc. In this case it is necessary to collimate the beam to obtain required size of a field on an object. Divergence of bremsstrahlung beam is determined by the electrons energy and the thickness of target. It can reach values about < θγ >∼30° for the electrons energy ∼ 5 MeV. On the distance L ∼ 500 mm between a radiator and an irradiated object the size of a beam must not exceed S ∼ 0.1L. This requirement is in order to prevent any distortions of defect image because of the beam divergence. In this article dependence of a "pattern" size on the distance L at a fixed size of a collimator located right on the betatron is investigated.
