Method for measuring tritium activity in a radioactive waste drum

摘要

The invention relates to a method of measuring the tritium activity of a drum (1) of radioactive waste containing a quantity of radioactive waste (2) and a free volume, the method consisting of measuring the quantity of <3>He produced by the decay of the tritium contained in said radioactive waste during a defined period of time and deducing from it the corresponding activity of the tritium contained in said radioactive waste (2).
