Visual photometry is widely used for deterntining the U content of molten NaF; the sensitivity and the precision of the method were greatly improved by the use of a photoelectric photometer. The experimental arrangement included a light source, a photomultiplier, a d-c amplifier and a supply system consisting of a ferroresonance voltage stsbilizer. Amounts of 10/sup -10/ g of U could be determined with the apparatus in about 4 mg of NaF with a reproducibility of results within 2%. The determination may also be carried out by measuring the intensity of the luminescence excited by the ultraviolet radiation of lambda = 366 m mu and of the visible radiation of lambda = 405 and 436 m mu and by determining the absorption of the 253.7, 313, 366, 405, 436, and 579 m mu lines of the Hg spectrum.
