Preparation of dead water for low background liquid scintillation counting


, : Preparation of dead water for low background liquid scintillation counting. Radioisotopes 36(3): 126-128

"Dead water", low level tritiated water is indispensable to measure tritium concentration in environmental waters using a low background liquid scintillation counter. Water produced by combustion of natural gas, or deep sea water etc. are usually used for the above purpose. A new method of reducing tritium concentration in natural water has been introduced for preparation of "dead water". This method is to combine hydrogen-oxygen mixture produced by water electrolysis with hopcalite catalyzer at 700.degree.C. Deep well water was electrolized up to 2/3 volume, and tritium concentration of recombined water was reduced to be about one third of that of the original one.
