Способ по п.1 или 2, отличающийся тем, что о величине утечки газообразного гексафторида урана и/или фтористого водорода судят по скорости уменьшения электрического сопротивления слоя лакокрасочного материала.5. Детектор, реализующий способ по п.1, содержащий электродную ячейку, состоящую из электродов, химически устойчивых к среде гексафторида урана и/или фтористого водорода, и разделяющих электроды электроизоляционного материала, химически активного к среде гексафторида урана и/или фтористого водорода, а также источник электрического тока, отличающийся тем, что электродная ячейка детектора выполнена в виде нанесенного1. A method for detecting a leak of gaseous uranium hexafluoride and / or hydrogen fluoride, comprising contacting uranium hexafluoride and / or hydrogen fluoride with the electrode cell of the detector and measuring an electric current flowing through the electrode cell, characterized in that the uranium hexafluoride and / or hydrogen fluoride are in contact with a layer of paint material in which powdered graphite filler is dispersed. 2. The method according to claim 1, characterized in that a constant electric current is passed through a layer of paint and varnish material in which powdered graphite is dispersed and its electrical resistance is measured; the leakage of gaseous uranium hexafluoride and / or hydrogen fluoride is judged by the change in the electrical resistance of the paint material. 3. The method according to claim 1 or 2, characterized in that the leakage of gaseous uranium hexafluoride and / or hydrogen fluoride is judged by the start of reducing the electrical resistance of the paint material. The method according to claim 1 or 2, characterized in that the amount of leakage of gaseous uranium hexafluoride and / or hydrogen fluoride is judged by the rate of decrease in electrical resistance of the paint layer. The detector that implements the method according to claim 1, containing an electrode cell consisting of electrodes chemically resistant to uranium hexafluoride and / or hydrogen fluoride, and separating electrodes of an insulating material chemically active to uranium hexafluoride and / or hydrogen fluoride, as well as a source electric current, characterized in that the electrode cell of the detector is made in the form of a deposited
