FIELD: medical technique.
SUBSTANCE: irradiator can be used in UHF-therapy. Irradiator for influencing of magnetic component of electromagnet field has two frames connected in opposition; ends of frames are connected with capacitors having similar capacitance; frames are turned one from the other. Adjacent sides of frames are open and third capacitor is introduced into breakage to connect both two first frames. Plates of third capacitor are connected with plates of two edge capacitors by crossed conductors. Sum of capacitances of two edge capacitors equals to 0,9-1,1 capacitance of third capacitor.
EFFECT: reduced power of parasitic radiation; improved precision of dosing of therapeutic radiation dose.
