A study was made of the theory that the light emitted from the moderator of a reactor of the same type as that at Fontenay-aux-Roses is produced solely by the Cherenkov effect. The spectroscopic study of the light emitted, carried out by comparison with a tungsten ribbon lamp, shows an energy spectrum distribution identical with that characteristic of the Cherenkov effect. The calculated brilliancy of the light source, assuming that all the light is produced by Cherenkov effect, is in good agreement. The variations in light intensity as a function of the running power of the pile were also studied. From this it is deduced that the light produced by Cherenkov effect corresponds to a source emitting about 2 x 16/sup 6/ photons per cm/sup 3/ of water in a spectral region ranging from 4,000 to 7,000 A, when the pile power is equal to 1 watt.
