FIELD: agriculture; veterinary science. SUBSTANCE: irradiator has two identical single-turn frames connected in opposition. They are symmetrical with respect to plane passing through centers of both frames. Ends of frames are connected to capacitors and turned away from each other. Frames are embraced by short-circuited turn which may be shifted from surface of frames in axial direction by value which is considerably less than frame sizes. Irradiator makes it possible to enhance accuracy of dosing of magnetic field action due to reduced electric component of electromagnetic field. EFFECT: reduced parasitic radiation. 2 cl, 2 dwg
