A sensitive and wide range method for the routine measurement of tritium in urine is described. Urine, distilled in the presence of toluene, is assayed for tritium content by a liquid scintillation technique. Two 1-in. diameter matched E.M.I. type 9524S/A photomultiplier tubes are connected through coincidence and discriminator units to a standard amplifier and scaler. The liquid scintillation counting is carried out at room temperature. A tritium concentration of 1 x 10/sup -3/ mu c/ml in urine gives about 160 cpm above a background of about 170 cpm. The counting efficiency is 7%. The absolute limit of detection of the method for tritium in urine is about 1.6 x 10/sup -4/ mu c/ ml, on the basis of two standard deviations. (auth)
