A dose of 1 gray to 30 gray is doped on the oscillating quartz. The oscillating quartz is inserted into a quartz oscillator (1) before the irradiation, where the oscillator is installed in an electronic circuit carrier before the irradiation. USE - Used for influencing an operating frequency of an oscillating quartz of a quartz oscillator that is utilized in a vehicle control system, personal computer, mobile telephone and control and regulating device of machines and plants. ADVANTAGE - The oscillating quartz is charged with the electromagnetic radiation with the wavelength less than 2.5 nano meter, thus enabling to change the operating frequency of the oscillating quartz to a specified rated frequency without additional electronic components in a simple manner.de620patent102005054745
