Abstract：
The decay of ^99mTc source was used to verify experimentally that in the measurement of the number of atoms of a radioactive isotope in a sample at time t₀, the error introduced through the inaccuracy of its decay constant (λ) can be reduced to a much smaller value by the careful selection of the time of measurement or measurements of its radioactivity at around one life time (1/λ) after t₀ and doing the calculation.
