Measurment of Tritium Concentration In Tigris River by Using Liquid Scintillation Counter Hadi K.D. , Amel N.W. , D.Salam K.A. Directorate Central Laboratories /Ministry of Science and TechnologyAbstractThe aim of this study was to measurment the concentration of tritium in water samples from the Tigris River, To prepare these samples to measure using liquid scintillation counter LSC technique were treated chemically with sodium hydroxide and potassium Bermnkenat to get PH No. = 11. The results were shown that the concentration of tritium element in all water samples that taken from tigris rever were within the permissible limits, and less than ( 740 Bq/L ) , according to the international Atomic energy Agency controls.Keyword :liquid scintillation counter LSC , Tigris river water .
