FIELD: medical engineering. SUBSTANCE: device has energy conductor manufactured on a base and member for controlling exposure. The conductor is unclosed spatial curve having intersecting coils belonging to not more than n-1 coordinate planes in n-dimensional coordinate system. Member for controlling exposure has reflecting surfaces and/or lenses and/or closed electric current-conducting circuits allowing changes in their position relative to the spatial curve and each other. The conductor optionally has members for connecting to electric circuit. The base is energy-sensitive and optionally contains materials of natural origin. To expose several areas of an object or several objects to energy influence, system is designed having at least two devices capable of changing their position relative to each other. EFFECT: enhanced effectiveness in protecting biological objects against external harmful radiation. 10 cl, 3 dwg
