DETERMINATION OF TRITIUM IN A PROPORTIONAL COUNTER (in French)
A method for the determination of tritium in the form of hydrogen in a counter of the Bernstein-Ballentine type operating in the proportional zone is presented. The filling is completed with methane up to a pressure of 760 mm Hg. The partial pressure of the tritiated hydrogen can attain 500 mm. With one tube a voltage of 4500 V is used for the measurement on the condition that the hydrogen pressure does not exceed 50 mm and that the total pressure does not vary more than 10 mm from its optimum value of 760 mm. The background is 90 counts per minute. No contamination of the counter tube by tritiated hydrogen is observed. The counting yield is quantitative for disintegrations produced in the cathode cylinder. The error for the complete measurement (introduction of the sample into the tube and counting) is 2%.
