DEVICE FOR MEASURING THE ENERGY DEVELOPED IN A NUCLEAR REACTOR OR IN ELECTRIC DISCHARGE EQUIPMENTS
When nuclear particles pass through a dielectric medium with a speed higher than the velocity of light in this medium, a radiation arises known as Cherenkov radiation. The intensity of Cherenkov radiation arising in a reactor is measured in order to determine the energy developed in the reactor. The dielectric medium is enclosed by a biological shielding through which a light guide passes for the transmission of the light component of the Cherenkov radiation to a point outside the biological shielding. This light guide follows a zig-zag path preventing the escape of dangerous radiation, e.g. gamma radiation. Outside the bio logical shielding a photoelectric cell is placed for measuring the intensity of Cherenkov radiation transmitted by the light guide. (NPO)
