- Edman274 2y agoWhen vacuum tubes have high voltages applied to them, they generate x rays. The glass envelope is impregnated with lead so as to reduce the amount of x ray radiation that is emitted. The primary source of x ray radiation from TVs had been from their other components other than the tube itself but the tube was still a source of ionizing radiation.
