A standard source containing 2.0 µCi (activity) of tritium, its half life is 12.26 years, a liquid scintillation counter measures 5% of its radiation and 120 cps are recorded which is a small fraction of the 2 µCi that were emitted by the sample. Calculate the activity of a sample for which the liquid scintillation counter gives a count rate of 270 cps. Dans CNC
